This is a good question and they're are two ways to approach this. First, we actually have pretty good hard data. In reality, Trump overseas business interests are pretty minimal. His business model for the most part is brand licensing which may or may not be a good thing 1/n https://twitter.com/LogTechEric/status/1319314744231088128

Going forward. From the information we have his income from foreign sources is actually relatively minimal and predates his time as President. Philippines, UAE, India others. Specifically in China, it's not large and he holds no assets I'm aware of. If I'm wrong let me know 3/n

Biden holds a 10% stake in a $6.5b fund turning out $130m a year in fee revenue. That one comparison makes Biden significantly more leveraged in China than Trump. Second, if we turn to potential embarrassing info that China might have on either very difficult to say 4/n

Really the only thing we can say is Trump by all records had minimal interaction with China prior to becoming President. We do know Hunter traveled their regularly from 2008-2019 and he is not shall we say an upstanding citizen. Beyond that it is speculation.
