Taiwan (ROC) is a bit of an odd duck because so many places treat them as different but don't do it 'officially' because China demands that they don't as part of maintaining relations with the PRC. For example the US sells them arms after all, it's not like the US completely refuses to admit they exist. Many countries have quasi-embassies in the form of Taipei Economic and Cultural Representative Offices (TECRO) which are definitely totally not embassies just act like them in pretty much every way.
