Not even the American government officially recognizes Taiwan as a sovereign nation.

Kinda sorta. The US treats Taiwan as a de facto sovereign nation, but doesn't give it de jure recognition because of the complications caused by the PRC's conditions for diplomatic relations. So focusing on "official recognition" is pretty misleading in this exceedingly weird case.
