The difference is that China is on Trump's enemy list, whereas he considers Russia's oligarchs to be potential business partners for his own oligarchy. Trump wants trade barriers to China but wants those with Russia to be removed.
I hear that a lot, but is it true? I don't see signs that this Admin is doing anything to prepare for a confrontation with the PRC; rather, signs of the contrary: TikTok ban reversed, conciliatory tone towards Xi, talk about a 50% reduction in defense spending, even nuclear disarmament, not to mention the mess DOGE is doing at the DoD. And Musk has significant exposure in China.
Of course, I'll be glad to stand corrected if I missed something.
Until the right Chinese person sucks up to Trump. Maybe someone with a less ..ehrm. . Asian look that Xi? (I don't know why, but Trump seems to admire Putin and despise Xi. . could be for all sorts of reasons, I guess)
