That's a rather obtuse, crass and mendacious statement. 1992 Consensus laid out that both sides of Taiwan strait recognize there is only one "China": both mainland China and Taiwan belong to the same China, though each side can interpret their own presentation of what one China means. UN, including the four other veto powers, recognize PRC as legitimate ruler of China, based on one China principle, which , given the still ongoing Chinese civil war, is to be understood as there may be two governments, but only one China.Taiwan was never in its history governed by the CCP, nor has the CCP ever held any sovereignty over that territory. A quick review of history shows that the first government on the island was established by the Dutch (who ousted the Spanish from their colony in the north), who were subsequently ejected by Koxinga, whose descendants in turn were defeated and the island annexed by the Qing, who in turn ceded the island to the Japanese, who in turn relinquished their sovereignity of the island in the Treaty of Taipei, wherein "Japan renounced all claim to them [Taiwan and the Penghu Islands] without specifying to what country they were to be surrendered". Since then, ROC has exercised sovereignty over the island.
Western powers have long meddled in China's internal affairs and still would like to have China weak and divided. Thus, the poisonous words of treason spread far and wide in MSM. Those rather dull minds like the perfect specimen quoted in above preclude the delicate and yet complex historical perspectives, instead falling back on boiler plate cliche thus clearly showing the lack of precise and refined understanding of the matter they foolishly try to comment on.
