Now you try to divert the point... WHO is an organization free for any independent countries to join. Obviously Taiwan is not qualify as independent, a nobody not recognized by any major countries.That's called political pressure. If let's say,the PRC was threatened to back down from whatever action,by the entire world community or else war....and you backed down,would you have said that the PRC is not independent or that it was just political pressure?
Doesnt matter China apply pressure or not. Fact is , it is not able to join and lost its right as an independent state. Even Hong Kong can join but not Taiwan.
