What is considered a safe haven for the Chinese Nationalists?

Answer 1

When the Chinese Communists defeated the Chinese Nationalists (Kuomintang/Guomindang) in Mainland China, the Nationalists retreated to the island of Taiwan (also known as Formosa) and established rule over the island. To this day, one of the dominant political parties in Taiwan is the Kuomintang (which goes under the moniker of "the Blue Party").

The irony is that because Kuomintang has unity with mainland China as an aspirational goal (as opposed to its political rivals which seek Taiwanese independence), the Communists in Mainland China prefer to negotiate with Kuomintang leaders in Taiwan than any other major Taiwanese political party.
