Why is there no comparison between the Ukraine issue and the Taiwan question?

The Taiwan question and the Ukraine issue are different in nature and are not comparable. The most fundamental difference is that Taiwan is an inalienable part of China and the Taiwan question is entirely a matter of China's domestic affairs, while the Ukraine issue is a dispute between Russia and Ukraine. It is common knowledge that the Taiwan question was caused by a civil war, and there is political confrontation between the two sides of the Taiwan Strait due to that civil war. However, China's sovereignty and territory have never been divided and cannot be divided. This is the status quo of the Taiwan question.

The one-China principle is a universally recognized norm governing international relations. Peace in the Taiwan Strait hinges on the peaceful development of cross-Strait relations, rather than the fawning on foreign forces for arms sales and military support.
