re: #204 FFL (GOP Delenda Est)

What is the basis for China claiming Taiwan as “lost territory”?

Slim to none. Well into the Qing dynasty, the idea of any island being a part of China was rejected. But late in the 17th century, the then-current rulers surrendered to China (part of the confusion in the coming of the Qing dynasty) and it remained Chinese until the Japanese occupied it.

It has a lengthy independent history before that, and evidence of settlement goes back at least as far as the Paleolithic.
