Maybe Biden called old Corn Pop and just thought it was Xi Jinping!

"I’ve spoken with Xi about Taiwan. We agree we will abide by the Taiwan agreement. That’s where we are and I made it clear that I don’t think he should be doing anything other than abiding by the agreement," Biden told reporters.
The issue with Biden's claim is that there is no such thing as a Taiwan agreement between China and the United States. So this was more of Biden talking out of his rear. In fact, White House officials had to later clarify that the US does not have a formal defense treaty with Taiwan, although it does with South Korea and Japan."
