I mean, if you look at China's actions over the last 3 years, especially with export controls, China probably wants an economic war, or at least has no desire to prevent one. Now that US bond market has spoken and China has a shot at actually cripple the entire US dollar system, and China already been prepared for a conflict, it's not in China's interest to stop.
IMO China should make sure Trump doesn't fold and keep increasing tariff to 200% or 400%, I know from my work that if you can't replace Chinese suppliers at 100% tariff, you can't at 200% or 400% either, but for American companies 100% tariff is a hit to bottom line, a big hit but just a hit, whereas 400% is death.
