No. If Taiwan still exists and controls its territory, either China vs Taiwan is a stalemate or it is a defeat for China.
So you think China is losing territory to Taiwan? Ukraine's claim is the same as China's claim in this matter.
In Iraq, the US invaded the territory with ease, but were unable to win, so they reached a stalemate and today the US continues to have military bases controlling territories in Iraq, sharing the territory with the Shiite government. It's a stalemate in every sense.
It seems you don't recognize any situation besides total win, total loss and stalemate. Let me introduce you to the idea of a partial victory. Not an unconditional victory but one side comes out on top.
Taiwan situation:
1. The Taiwan situation exists because of the civil war. It makes sense to evaluate the entire civil war in that case.
2. The goal of RoC was elimination of the PRC. The goal of the PRC was elimination of the RoC. The way to eliminate another polity is to reduce their area of control to 0. I am not aware of an alternative method.
3. PRC reduced area of RoC control by 99% before the conflict was frozen. Therefore the PRC has a partial win, as the settlement is favorable, but not complete. It is not a stalemate.
4. A stalemate implies that the 2 parties came out equal. Chiang did not want to lose 99% of his territory. He was not better off now (defined as closer to completion of goals) than he was at the start of the conflict. Mao did want to gain 99% of China's territory. Mao is better off than he was at the start of the conflict. Therefore Mao won.
Iraq situation:
1. The Iraq situation exists because the US wanted more control over Iraqi oil and to install a US friendly government. The US already had bases throughout Saudi Arabia, Qatar and Jordan. Iran's primary goal was elimination of a hostile Iraqi government and the establishment of a pro Iranian, pro Shia government. That had been its goal since 1980 with the start of the Iran Iraq War. It's secondary goal was to prevent the US from achieving any conflicting goals.
2. Today the Shia government has become entrenched and China is one of the biggest buyers of Iraqi oil. The US is a negligible customer of Iraqi oil. US bases are redundant, but it is a minor win.
3. Since the US achieved some goals in Iraq, but Iran achieved all goals in Iraq except for prevention of US achieving all goals, this is a partial Iranian victory.
In fact I'll comment on Kosovo too. If it's a stalemate then Yugoslavia and NATO walked away equal. But they didn't, as Yugoslavia no longer exists but NATO does and now includes former Yugoslavian states. It doesn't matter that Serbia still exists as a rump state, NATO won most of its goals.
