"@Brad_Setser @GlennLuk And Russian policy and a lot of Chinese fiscal policy can been seen through the lens of national security. China wants to keep deficits and debt low so if there is a trade/military crisis it has enough fiscal reserve"

"@robin_j_brooks @FrensWuiMade @yieldsearcher Goes to Russia or Mars. All I care about is that the bank gets the wire from Dubai and this goes in my account. So I ship my iPhones to UAE or Thailand and if they resell to Russia none of my concern"

"@Glenn_Diesen Also you note that China started dropping during Trump XXX and my thesis is that the inflation during COVID was due to China and Russia refusing to fund the US. Because the US can't get cash from China and Russia it is desperately trying to squeeze money from its "allies""

"@onechancefreedm @robin_j_brooks @M_C_Klein China is going super into high tech right now. We aren't peasants growing rice. Global trust You are kidding me. Look I try to be polite but people are so delusional that it's hard for me to stomach it. You believe what you want and I'll just wait for reality to hit"

"Funding in China is incredibly decentralized because you have different funders and govts each with different pools of capital. One reason I think the why the system works is that the people that decide priorities aren't the people that decide funding"

"@robin_j_brooks First of all I don't trust AI to do research. AI gets things wrong. For example I've posted the fishing boat registry. Yes my story does change every day. It's called learning new stuff and changing my views to fit the facts and new information"

"@robin_j_brooks If you look at the sectors that China is exporting in and the deals you will see that most of them were set up before Trump did his tariffs which means that you would see an export bump without Trump and this makes sense because with all of the talk about decoupling"

"HAHAHAHAHA. Funny to have someone argue that you don't exist. He is arguing that China can't surpass the US because somehow the US has this monopoly on creativity and dynamism. (i.e. people like me don't exist in China)"

"@Brad_Setser @GlennLuk Also one big reason that the Central Government does not want to increase fiscal spending is Donald Trump. If Trump starts another trade war or God forbid we get ourselves in a shooting war over Taiwan CG will need to push fiscal spending through the roof"

"@onechancefreedm @robin_j_brooks @M_C_Klein Also you forget one big thing. The US is unwilling to run trade deficits with China. So the system is over. Trump wants the US to stop running trade deficits at which point the whole freaking system falls apart. People in China are working on the new system"

"Here is the counterargument. The numbers show that the state banks have dollars. There is no breakdown in who controls the dollars. The Chinese currency system is such so that anyone with dollars can move them into a state bank"

"@robin_j_brooks @MarkSimonHK @Brad_Setser But that means that if a US customer backs out they have a customer from somewhere else that wants to buy their stuff. Also they because they are in a situation of perfect competition they have infinite price elasticity"
