We can go back and forth about this, but political feelings aside, although Taiwan acts like an independent state and has its own government, no important independent state treats it like an independent state, including the US. Donald Trump is the first president in four decades to even send a cabinet-level official to Taiwan when Alex Azar went to visit last month. It is what it is. Whether you like it or not, no important country has official diplomatic relations with Taiwan because they've all agreed to the One China policy. It is partially because of this One China policy that Taiwan's economy has deteriorated so much, they are not on equal footing with other countries in being able to develop trade agreements with other nations. China has them boxed in.
