@dood111said Trump wasn't president then and his account in China has been inactive since 2015.
Plus he has paid millions in taxes in the US, contrary to your claim.
Biden took in millions from China Russia Ukraine when he was Vice President and never claimed it.
Trump would have loved a deal with China before the election but as usual he overestimated, miscalculated and played right into China’s hands. With their economic muscle they will never need to make a deal regardless of who sits in the White House.
