Bottom line: Can Taiwan trust CCP China to keep its words? NO. End of story.

Taiwan, for all intents and purposes, is an independent, democratic, flourishing nation with an armed forces, diplomatic corps and president elected by the population. The people have unfettered access to media, the internet and enjoy due process under the law...not to mention a decent socialized medical system China can't even come close to. 

China would love to END all that and oppress the entire island nation under the corrupt criminals that also control the CCP.
