There is a lot more room for China to put pressure on large US firms/stock market. Software licenses and play store fees. Export taxes on electronics that are permitted to US.
Big one is war on/for allies, and a warning against excess sycophancy to US. But hot war in middle east/panama, or offering a better deal to Ukraine that just giving every asset to US in exchange for nothing, or seizing their share if Europe makes wrong decisions. The big problem with trade shutdown is war becomes much easier choice to keep people employed. Ordering US fleets to leave Israel's offense support and ordering Netanyahu/cabinet to resign and report to ICJ prison (as ultimatum to not destroy Israel), is the correct pressure point to get US to submit fully to China.
