- speaking of China the country is shelling out nearly a trillion and a half dollars to tackle its local government debt problems China has
- approved a staggering 10 trillion un or $1.4 trillion debt package to bolster
- its struggling economy this action comes as a shock to many especially the United States which has been dealing with its
- own economic challenges and the return of Donald Trump to the White House Finance Minister Lan faan announced the
- details of this massive debt package at a press conference over the next 3 years Regional governments will be allowed to
- borrow up to 6 trillion un or $838 billion to replace their hidden debt
- which is typically owed by risky local government financing platforms additionally local governments will have
- access to a separate 4 trillion un or $558 billion quota for special local
- bonds over the next 5 years aimed at further reducing their debt Holdings well that 1.4 trillion is supposed to be
- 1:00
- stimulus but it's not stimulus in the traditional sense in that it's not being used to stimulate demand so 60% of it
- has been allocated to a program for local governments to issue new bonds over three years including this year to
- pay off what the government calls as hidden debt so this is debt that's off balance sheet or um unrecognized which
- has been a primary source of risk in this economy so in addition to that uh local governments will be allowed to
- issue more special bonds over 5 years to raise funds for the same purpose uh the
- stimulus is indirect so the Finance Minister said that $85 billion over five
- years would be freed up uh because of this refinancing of the debt that local
- governments would be able Lan stated since the beginning of this year affected by a variety of factors the
- Central and local government fiscal revenues have fallen short of expectations China's decision to
- 2:00
- implement such a drastic measure stems from its recent economic struggles since
- the beginning of 2023 Central and local fiscal revenues have fallen short of
- expectations largely due to years of tight pandemic restrictions and a crippling real estate crisis
- consequently local government coffers have been drained leaving authorities across the country grappling with
- mountains of debt and few resources to kickart economic growth the problem has
- become so so severe in some areas that cities are now unable to provide basic services and the risk of defaults is on
- the rise Lan foan revealed The Staggering scale of China's hidden debt which stood at 14.3 trillion un or $1.99
- trillion at the end of 2023 the government's goal is to slash this
- amount to 2.3 trillion un or 320 billion by 2028 while some analysts see the debt
- package as a step in the right direction others remain skeptical about its Effectiveness Mark Williams Chief Asia
- 3:04
- Economist at Capital economics noted that the package only amounts to about 0.5% of China's current gross domestic
- product spread over 5 years clearly that's not going to make any appreciable difference he wrote in a research note
- today's fiscal announcement is another disappointment for those expecting substantial stimulus on the other hand
- Larry who Chief China Economist at mcor bank believes the scale of the debt swap
- exceeds expectations however he also pointed out that it is unrealistic to
- expect the national people's Congress to approve a massive fiscal package as the
- policy goal is to achieve the GDP growth Target and reduce risks not to meaningfully reflate the economy it may
- be disappointing for those who are expecting the NPC meeting to approve a massive fiscal package but the
- expectation is unrealistic because the policy goal is to achieve the GDP growth
- 4:02
- Target and reduce tail risks not to reflate the economy in any meaningful
- way he said China's economic challenges are indeed daunting in the third quarter
- of 2023 the country's GDP grew by just 4.6% compared to the previous year only
- slightly higher than the 4.5% forecasted by economists pulled by Reuters there is a real risk that
- Beijing may miss its annual growth Target of around 5% after a summer of
- dismal economic news China's leader XI Jin ping finally decided to move forward
- with a much-needed stimulus package in late September primarily focused on monetary measures since then economists
- have been anticipating additional stimulus measures worth up to 10 trillion un to restore confidence in the
- world's second largest economy it is important to note that China's debt swap
- program is a departure from its previous allout stimulus strategies instead of directly injecting money into the
- 5:04
- economy this plan aims to repair Municipal balance sheets as a longer-term objective Finance Minister
- Lan faan has signaled that more stimulus is on the horizon with some analysts suggesting that Beijing may be saving
- ammunition for a potential trade War under a second Trump Administration the measures announced by China confirm the
- scale of the local government debt crisis the international monetary fund estimates that hidden debts amounted to
- 60 trillion when 47.6% of GDP at the end of 2023 although
- China puts the figure at a lower 14.3 trillion un the debt swaps are expected
- to save local governments 600 billion UN in interest payments over the next 5
- years swapping hidden for official debt is expected to save 600 billion W in
- interest for local governments over five years Reuters reported Lan foen also
- 6:02
- reiterated additional support measures such as policies to support state sector purchases of unsold Apartments
- reclaiming undeveloped residential land from developers and replenishing the capital of big State Banks be able to
- spend uh the Finance Minister also added that new measures would promote State purchases to buy idle land and unsold
- homes so that in theory would help the property sector but uh there's nothing in this plan that directly help helps
- and gets money into the hands of consumers and companies to stimulate
- demand however he did not provide details on the size or timing of these more direct stimulus measures Lan also
- reiterated officials will issue policies to support state sector purchases of unsold apartments and reclaim
- undeveloped residential land from property developers as well as replenish the capital of big State Banks Reuters
- noted many economists argue that stronger consumer stimulus is needed to revive China's economy the country faces
- 7:03
- tariffs on its exports from the US and other nations while low wages High youth unemployment and a weak social safety
- net keep household spending low China's household spending is below 40% of its
- GDP which is 20 percentage points below the global average analysts believe that
- Beijing is likely holding back some stimulus waiting for more clarity on Trump's China policies before acting
- they may also want to avoid the appearance of overreacting to the US election policy makers probably saw no
- need for a robust response to Trump's Victory before he takes office given the relatively restrained post-election
- Market response said Duncan Wrigley Chief China Economist with Pantheon
- macroeconomics next year is a different matter but officials will take that as it
- comes Market reactions to China's debt package announcement have been mixed
- 8:00
- some investors were disappointed by the lack of details on additional fiscal spending to directly stimulate the
- economy While others had expected support for purchasing property inventories the uan weakened against the
- dollar following the announcement and East Asian equities initially extended gains but later retreated to really have
- a positive for markets you want to see something which is 2 trillion or above specifically talking about consumption
- related stimulus Bernie akong CIO at UBS o Conor Global multistrategy Alpha told
- Bloomberg TV chenl hang an expert on the Chinese economy at the Peterson
- Institute for international economics said what they have announced is a package meant to manage risk stabilize
- the economy to prevent it from falling further instead of directly stimulating domestic demand which is actually what I
- think they should do because I think the number one challenge the Chinese economy faces now is
- deflation Wong said that Beijing has a fundamental opposition to handing out
- 9:03
- cash they don't like welfarism he said adding that Chinese officials think it would encourage people to become lazy
- investors are now closely watching for the December pollit Bureau meeting and the central economic work conference
- where greater Clarity on the US trade stance and China's fiscal strategy is expected right uh yesu we know that
- Beijing had an earlier signal that fiscal stimulus is coming but you know as Olivia had mentioned it was short on
- detail frustrating uh investors so essentially at this point do you think investors are generally going to be
- happy with today's announcements I think that's a great question thanks for asking I think it's
- really a mixed result today and I'm not I'm not sure that all of the investor will feel happy because there are two
- things that investors are watching one is the amount of that swap as Olivia
- mentioned is 10 trillion or 12 trillion already right already the other thing that investors are watching is how much
- 10:02
- additional fiscal money fiscal bond that the government is willing to take uh to
- stimulate the economy however the second part as I mentioned there's not much mentioning on the additional fiscal
- spending um uh in details this time so that's I think uh where the the the
- broader um P mistake come from the geopolitical context and trade tensions cannot be ignored when considering
- China's economic moves the the debt package announcement comes just days after Trump's reelection and the
- president has threatened tariffs of up to 60% on Chinese Goods adding uncertainty
- and complicating China's economic challenges during his first term Trump
- launched a trade war with tariffs on $360 billion of Chinese Imports despite
- these challenges robust Chinese exports have been a rare bright spot this year
- however Trump's Victory May undo beijing's economic stabilization efforts analysts expect China to launch stimulus
- 11:04
- measures in stages escalating and deescalate as the US trade stance
- becomes clearer they may not substantially boost stimulus until Trump's specific actions are known
- Beijing is launching a stimulus largely to repair confidence said Gerard Depo
- senior geoeconomics analyst for Bloomberg economics and if the US is basically declaring a second trade War
- it might undo those stabilization measures on the confidence side certainly with foreign investors and
- possibly with Chinese households so that would be a rather big problem for Beijing critics of China's debt package
- point out its limitations particularly its focus on supply side measures rather than boosting domestic demand this
- approach May exacerbate industrial overcapacity and trade tensions without
- a rebound in consumption producers cannot absorb inventory during export shocks which would hurt profits revenues
- 12:01
- and dampen private investment or trying to boost domestic
- demand Rebecca I'm having a little bit of deja vu when you look at this Market reaction because about a month ago we had a similar one from the ndrc and I'm
- curious how much of that Dynamic has actually changed to your point they're falling short on that key word
- consumption I think that's the really big missing piece here and by the way there was never particularly a promise
- but actually there just had been a lot of speculation and a lot of expectation there had been some media reports for
- example that suggested that China was actually going to set aside a hefty chunk of change into buying unsold
- property for example now that hasn't transpired today perhaps you can kind of link that to some of the Commodities
- declines that we've seen in markets too and so again there was also this bet
- that uh if we saw a trump victory that Beijing would turn and sort of have its
- hand forced into trying introduce more support particularly focusing around restoring domestic
- 13:05
- consumption as Yu principal China Economist at The Economist intelligence unit noted thing is that if the
- consumption domestic consumption cannot come back which means that whenever there's an export shock either because
- of tariff increase that means that the producers within China couldn't find uh
- like ways to absorb their inventory that would dampening their profit their
- revenue and again depening private invest some argue that direct household income support is needed to boost
- consumer spending and sentiment additionally debt swaps do not address the underlying local fiscal Revenue
- shortfalls meaning local governments will still need to borrow to fund basic operations as Victor shei a specialist
- in Chinese politics and finance at the University of California San Diego stated it's really not going to address
- the problem in a meaningful way there will be round after round of these small bailouts to make sure that things don't
- 14:02
- get out of control but the underlying debt amount will still rise the stimulus
- package is also smaller than some expectations especially considering the Tariff risks posed by Trump at around
- 0.5% of GDP per year it is well below the 10% plus of GDP in the 2008 crisis
- stimulus Carlos kasanova Asia senior Economist at ubp estimates that China
- needs closer to 23 trillion un to reduce housing inventory and hidden debts the
- measures announced on Friday are going to disappoint the market because China needs more essentially he said
- furthermore the money is largely being used for infrastructure and property rather than direct household support
- while boosting investment helps employment and income growth gradually there is a lack of funds being
- distributed directly to families as seen in the US Co stimulus I don't think that
- we we will see direct fiscal stimulus aimed at consumption anytime soon ub's
- 15:04
- Casanova said I think you will need a lot more pain for that to materialize he
- added China is probably going to hold back some of that Firepower until they have a better idea of what president
- Trump is planning according to Yu's research group the impact of the tariffs on
- Chinese Goods could be significant she said to your research group though how big of an impact do you expect the
- tariffs to have Chinese Goods after all I mean boosting exports has been one of
- the growth drivers for China this year yeah that's a good question
- according to our estimation if Trump Administration impos 30% tariff on
- Chinese product in general that would uh reduce China's GDP growth by 0.3 to 0.4
- percentage Point within within the next two years I mean 25 and 26 however as we
- can see that if the Congress is being controlled by the Republican that means that it's potentially there's higher
- 16:05
- risk that the Tariff could goes higher and could comes much earlier that means that there is significant downside risk
- to China's export next year in 2026 which means that I do expect the government will come up with a stronger
- fiscal policy uh especially focus on consumer goods spending when considering the various
- pillars of the stimulus measures yesu believes that managing Market expectations is a top priority for the
- government she explained I think the the S the most important thing in the government mind I
- think the top thing is actually to manage Market expectation again so you
- can see that throughout uh from the December end December to now there are several conference uh press conference
- uh hosted by the government officials and they keep sending the positive signal to the market so I think M manage
- Market expectation to domestic event s and foreign investor are the top priority of the government the second
- priority is to reduce systematic risk in the banking sector and uh and amount the
- 17:07
- local government China's 10 trillion un debt refinancing package for local governments is a substantial move that
- caught the US offguard however many analysts believe it falls short of the fiscal Firepower needed to reinvigorate
- the sluggish economy particularly in terms of spurring consumer Demand with the risk of a renewed trade War under a
- second Trump Administration Beijing may be holding some stimulus measures in reserve imagine a high-speed Journey
- under the East China Sea China's gintong undersea tunnel is making it a reality
- this 16 km record-breaking tunnel will cut travel time between Ningbo and Joan
- to 26 minutes overcoming extreme underwater pressures and complex seabed

- the transformative impact this will have on the lives of the people in these two cities as they are seamlessly connected
- to each other and to the larger high-speed rail network that spans the length and breadth of China but the
- benefits don't stop there the new tunnel will also also serve as a crucial link connecting the Joan Islands to China's
- extensive high-speed rail network Envision the journey between Joan and hjo which currently takes about 3.5
- hours being reduced to a mere 77 minutes it's a game changer that will
- undoubtedly accelerate the integration of Ningbo and xan into the yangi river
- economic belt the yangi belt is China's largest economic zone sprawling across

- 23:57
- under the water currently hold the titles of the world's longest undersea tunnels however the jintong undersea
- 24:05
- tunnels unique distinction is that it is specifically designed for High-Speed Rail allowing trains to travel at speeds
- 24:12
- of up to 250 kmph through the depths of the East China Sea speaking of
- 24:18
- High-Speed Rail let's take a moment to appreciate the sheer scale and dominance of China's Transportation network with
- 24:25
- over 46,000 km of highspeed rail tracks in operation the country accounts for
- 24:31
- More than 70% of the world's total high-speed rail network from the bustling metropolises of the East to the
- 24:37
- remote regions of the West China's high-speed rail network has transformed the way its citizens move and connect
- 24:44
- imagine traveling on a train in Beijing and arriving in guango in a matter of hours or traversing the vast expanse of
- 24:51
- the country from harbon to Kunming in a fraction of the time it would have taken just a decade ago it's a revolution in
- 24:57
- trans portation that has propelled China to the Forefront of the global stage and
- 25:03
- the country's Ambitions don't stop there with plans to expand this network even further China is determined to redefine
- 25:10
- the boundaries of what's possible in the world of High-Speed Rail the gintong undersea tunnel is just the latest
- 25:16
- chapter in this ongoing saga but China's vision for the future of Transportation doesn't stop at its borders in an
- 25:24
- interesting proposal the country has set its sights on an even more audacious project a $200 billion underwater train
- 25:31
- Network that would connect mainland China to the United States traversing through Siberia Alaska and Canada along
- 25:38
- the way imagine boarding a high-speed train in Beijing and reaching New York City all while traversing the depths of
- 25:44
- the ocean it's a concept that sounds like something straight out of a science fiction novel but China is determined to
- 25:51
- make it a reality with a proposed length of over 12,800 km this underwater rail net work
- 25:58
- would dwarf even the most ambitious of engineering projects setting a new standard for Global connectivity the
- 26:05
- plan was first announced in 2014 and received a lot of media attention
- 26:10
- however some say the project has been put on hold the feasibility of this project may be the subject of much
- 26:17
- debate but it proves China's unwavering ambition and its willingness to push the boundaries of what's possible after all
- 26:24
- the gintang undersea tunnel was once just a bold idea and now it's well on its way to becoming a reality who's to
- 26:31
- say that the underwater train Network won't one day follow in its footsteps as we've already established the gintang
- 26:38

- for the jintang undersea tunnel project at China Railway 11th Bureau group the
- 27:08
- next phase will fully shift to Marine construction which brings even greater
- 27:14
- challenges the tunnel will take the Ningbo Joan line beneath a busy shipping Lane in the East China Sea that is used
- 27:21
- by vessels up to 100,000 tons in size it has been described as the longest

- Japanese mountains lies a glimpse into the future of Transportation a 43 km
- 28:50
- magnetic levitation train track that defies gravity this isn't Science Fiction it's Japan's ambitious maglev
- 28:57
- project where trains hover 10 cm above their tracks and hurdle through space at
- 29:02
- a mindbending 500 kmph the technology behind these floating trains sounds almost magical
- 29:09
- but it's grounded in sophisticated engineering and Decades of research unlike conventional trains that rely on
- 29:15
- Wheels and tracks these trains literally float on magnetic fields but before we begin how this
- 29:22
- revolutionary system works let's look at where maglev technology stands today
- 29:27
- does despite the futuristic promise of magnetic levitation technology its realworld implementation remains
- 29:34
- surprisingly limited currently only one commercial high-speed maglev line
- 29:39
- operates in Daily service the Shanghai maglev connecting pong International Airport to the outskirts of shanghai's
- 29:46
- financial district this 30 km route while technologically impressive
- 29:51
- actually highlights some of mlv's current limitations the journey takes just 8 minutes but here's the fascina
- 29:58
- Paradox despite the Train's capability to reach speeds over 400 kmph its
- 30:04
- average operating speed is only 225 kmph why because on such a short route
- 30:12
- the train barely reaches its top speed before it needs to begin slowing down it's like having a Formula 1 car but
- 30:19
- only being able to drive it on a short City Block to put this limited implementation into perspective let's
- 30:25
- look at conventional High-Speed Rail net networks traditional high-speed trains currently operate on an astounding
- 30:32
- 60,000 km of track worldwide China alone has built over
- 30:38
- 40,000 kilometers of these lines in just two decades Japan's shinkansen Network
- 30:44
- spans 3,000 km while Europe's various high-speed networks connect major cities
- 30:50
- across the continent even more telling is the ongoing expansion an additional 50,000 km of conventional high-speed
- 30:57
- race are currently under construction globally countries from Morocco to Indonesia are building new lines showing
- 31:04
- the continued Faith In traditional wheelon rail technology what makes this disparity even more striking is that
- 31:12
- maglev technology isn't new it's been around since the 1970s yet in nearly five decades only
- 31:19
- Shanghai has managed to implement a high speed commercial line several other projects like the Birmingham Airport
- 31:25
- maglev in the UK and the Berlin bon in Germany operated briefly but were eventually decommissioned due to
- 31:32
- maintenance costs and reliability issues multiple countries have conducted feasibility studies for maglev lines
- 31:39
- Germany's trans rpid project America's proposed Baltimore Washington route and various Chinese corridors but most have
- 31:46
- opted for conventional High-Speed Rail instead the reasons range from cost
- 31:51
- considerations to compatibility with existing infrastructure this context makes Japan's current maglev project
- 31:59
- even more remarkable it's not just building a new train line it's betting on a technology that has struggled to
- 32:05
- find widespread Commercial Success there are two main approaches to making trains levitate the first used in shanghai's
- 32:12
- system is electromagnetic suspension essentially pulling the train upward using attractive magnetic forces this
- 32:19
- method requires maintaining a precise gap of 8 to 12 millimet between the train and track it's like trying to hold
- 32:26
- a magnet steady below another magnet the closer they get the stronger the attraction becomes making the system
- 32:33
- inherently unstable and requiring constant computerized adjustments Japan
- 32:38
- chose a different path their system creates a 10 cm gap eight times larger
- 32:44
- than shanghai's and achieves stable levitation through magnetic repulsion at
- 32:49
- the heart of Japan's lzo train lies a Marvel of modern engineering its revolutionary superconducting magnetic
- 32:56
- system each train car is a equipped with eight powerful superconducting coils precisely arranged with four on each
- 33:03
- side transforming the basic principles of magnetism into a practical Transportation solution these aren't
- ordinary magnets you'd find on your refrigerator the coils are made from niobium titanium a special alloy that
- becomes superconducting when cooled to extremely low temperatures superconductivity is a fascinating
- phenomenon where electrical resistance completely disappears allowing electric
- currents to flow indefinitely without losing energy but achieving this state requires maintaining temperatures close
- to absolute zero to accomplish this feat each coil is cooled using a sophisticated dual temperature system
- the niobium titanium coils are bathed in liquid helium at a bone chilling minus 269 de C 4 Kelvin while a surrounding
- jacket of liquid nitrogen atus 196° C provides an initial cooling
- barrier think of it as a Russian doll of cooling systems each layer protecting
- 34:04
- and supporting the next the real engineering breakthrough comes in the form of the pulse tube refrigerator
- system this ingenious device maintains these ultra low temperatures without any moving Parts in the cold section making
- it more reliable and less prone to Mechanical failure the system works by
- creating pressure waves in helium gas similar to sound waves which create alternating hot and cold regions through
- careful timing and heat exchange it can maintain the superconducting state indefinitely but having such powerful
- magnetic fields on a passenger train creates its own set of challenges the magnetic fields generated by these
- superconducting coils are strong enough to wipe credit cards interfere with pacemakers and attract metallic objects
- clearly not ideal for a public transportation system this is is where the magnetic field management system
- 35:00
- comes into play the engineers developed a sophisticated shielding solution using
- electric steel containing 3% silicon this isn't your ordinary steel it's
- specially processed to align its crystal structure in specific directions allowing it to channel magnetic fields
- like a router directs internet traffic the steel undergoes a complex Cold Rolling process that creates large
- aligned Crystal grains these grains can carry about 30% sent more magnetic flux in the desired Direction enabling
- Engineers to precisely control where the magnetic fields flow it's like creating
- invisible magnetic highways that direct the fields away from Passenger areas the
- results are impressive inside the passenger compartments the magnetic field strength is reduced to just 0.5
- millitesla comparable to Earth's natural magnetic field for perspective that's less than 1% of the field strength you'd
- experience during an MRI scan the tracks themselves need special consideration
- 36:00
- traditional steel rails would be attracted to the powerful magnets creating unwanted forces and
- interference instead the system uses a combination of low magnetic steel and
- fiber reinforced composits for the guideway structure these materials maintain their structural Integrity
- while remaining magnetically neutral the entire system requires incredible Precision in both manufacturing and
- assembly the superconducting coils must be wound perfect the shielding materials need to maintain their properties over
- Decades of use and everything must be aligned with millimeter Precision it's
- like building a Swiss watch but one that's several kilometers long and operates at temperatures colder than
- space each component must also be designed to handle the extreme forces
- involved when operating at 500 km hour
