China should be ready, the US ruling class see this as their last chance of window for a full court press to crush China's economic and technological development, never to let China rise again if succeeded. Either that or for Chinese leadership to agree to self imposed containment in face of all the unreasonable demands that will be upcoming.
Don't underestimate a desperate beast's will to shore up her hegemony by any means. The world is never about fairness to begin with, I hope China dont forget past lesson and soften up in hope of reconciliation.
You talk as though Biden hasnt been trying to do exactly that for last 4 years. Its not about desire, its about ability, America does not have the ability stop China, Trump's difference with Biden is only in how much damage he can do to the US itself in his failed attempt (see COVID) and thats what makes Trump the prefered candidate for China.
Also if tariffs are remotely relevant you wouldnt have forgoten 2018 tariffs are ALL still in place, the trade war never ended, America just lost, and if Trump doubles down they'll lose even more badly, Americans will be even less able to affford anythibg, and you'll again forget it happened in 4 years.
Honestly the worst Trump can do right now economically is to actually end the tech war and remove all export restrictions, I dont think Chinese companies will forget the risk but some might ignore it out of convenience, and that will slow down growth in China's own tech industry.
