I don't disagree that Trump could probably stop the TikTok ban for now, but all these things about long-term coexistence with China are not very realistic. That's a very long shot, if we understand that Trump HIMSELF and his party kickstarted this whole trend of escalation toward China that later also became bi-partisan. To think that they would stop now after China became an even stronger, multiple orders of magnitude threat than ever before is crazy.
Edit: Will Trump stop with tech sanctions, economic sanctions, tariffs, political provocations regarding Taiwan, military posturing, etc, the answer is 100% no! A few cordial diplomatic ceremonial symbolic meetings won't be able to change that fact about the clear trendline that exists now.
