Politically yes, Taiwan is de facto independent, but economically they are deeply intertwined; although they have their own currency, stock exchange etc., a lot of major companies operating in China are under Taiwanese ownership (Foxconn and Pegatron for example) and the commerce between China and Taiwan is significant; China is Taiwan's largest trading partner at 30% of Taiwan's total trade.

By contrast, China is the US' third largest trading partner (after Canada and Mexico) at 10% of US trade. Taiwan is much more intertwined with China economically. Which makes sense given the geographic proximity and linguistic and cultural ties.
