China claims the democratically-governed island as its own territory and has over the past two years or so increased its military pressure against Taiwan, having never renounced the use of force to bring it under Beijing's control.
Both China and Taiwan's governments agree that Taiwan and Ukraine's situations are different, but for different reasons.
China says Taiwan has never been an independent country, while Taiwan says it is inappropriate to make a link as major chip-maker Taiwan is more important geopolitically, and that unlike Ukraine and Russia it shares no land border with China.
Chinese Foreign Minister Wang Yi said the Taiwan and Ukraine issues were "not at all comparable" as Taiwan was a domestic matter for China, while Ukraine was a dispute between two countries.
"We have seen that some people emphasise the principle of sovereignty on the Ukraine issue, but continue to undermine China's sovereignty and territorial integrity on the Taiwan issue. This is a naked double standard," he said, in apparent reference to the United States.
Washington is Taiwan's most important international backer and arms supplier, a frequent source of friction in Sino-US ties.
China recognises no sovereignty claims by Taiwan's government, which in turn says the People's Republic of China has never ruled the island and only the Taiwanese people can choose their future.
Wang, speaking at his annual news conference on the sidelines of China's annual parliament meeting, said tensions were Taiwan's fault for the government's refusal to accept they were part of China, which will "ruin Taiwan's future".
He said hoped Taiwan's future lay in the peaceful development of relations across the strait that separates them.
"In the end Taiwan will return to the embrace of the motherland."Â
