Huh? The PRC has said Taiwan and the mainland are one country since 1949, and the Taiwanese government has said the same since 1949. The previous Taiwanese president, Ma Ying-jeou, said this all the time.
All that Taiwan wants is to stay independent and democratic.
Do you have a good source on this? I just searched it and DDG didn't come up with any news source I know is reputable. The first 5 links I get are: newsmax.com, news.com.au, theglobeandmail.com, france24.com, and tibetsun.com
"We do not promise to renounce the use of force and reserve the option to use all necessary measures."
Taiwan has to say this. China views Taiwan relinquishing their claim to the mainland as a deceleration of independence and justification for invasion.
