Why does western media keep referring to Taiwan as if it was a country as opposed to a province of China?
Taiwan is part of China. This is a well documented fact, and Taiwan's legal standing is not in question. This is the position held by the UN, and it's the fundamental basis for having diplomatic relations between US and China per Potsdam Proclamation that was signed 77 years ago between China, the US & the UK. This position has never officially changed.
