Trump (and Elon) are actually fairly pro-China. Or at least, Trump and Xi have a good relationship (and Trump was quoted last month as believing the US and China can solve many problems together), and Elon loves China.
They’re pro-themselves. China could bankrupt Musk at the stroke of a pen by kicking Tesla out, so he’s effectively their foreign agent. Trump wants bribes, and he has leverage via his unchecked power over tariffs. He even opened a convenient collection box via his cryptocurrency.
