Actually, the UN (and technically the U.S.) has already “decided”: Taiwan is part of China. Taiwan is not recognized as an independent nation.
Wrong
its recognizes the communists as the government of the mainland
following the 1949 civil war the Nationalists fled to Taiwan and for 20 years were recognized as the rulers of ch8na
but that was unsustainable if I recall red china was admitted to the UN about 1972.
now the popular opinion in Taiwan is moving toward independence.
something the communists are opposed to
if that happens it could lead to war
