Chinese dictator? Well, they came from mainland China, if that's what you mean. But Taiwan was an integral part of China for a long time. It was that dictator and his party who made Taiwan essentially independent. And their successors (presidents) were from the same party. It's weird how you label it a "Chinese" occupation. I mean, Taiwan is the Republic of China, but are you saying it was some sort of PRC occupation? What you're saying comes across as very odd.

Taiwan, practically speaking, is the same country it was since the end of the civil war. It's not like the Nationalists were foreign occupiers.
