A couple more points.
Only 14 other states officially recognize Taiwan as an independent, sovereign state. No state recognizes both the PRC and the ROC. The PRC has established non-recognition of the ROC as a fundamental baseline for diplomatic relations, and 179 of the 193 UN member states acquiesce. Indeed, for decades the ROC itself followed the same policy.
Taiwan is a member of a few international and intergovernmental organizations, generally under convenient circumlocutions. For example, Taiwan competes in the Olympics as “Chinese Taipei.” But the PRC has blocked, and continues to block, Taiwan’s accession to various international and intergovernmental organizations, treaties, and regimes.
And over the last 20 years, the PRC has only intensified its efforts to diplomatically isolate Taiwan. It has used its growing economic clout, and diplomatic, economic, and financial carrots and sticks, to convince countries to switch their official recognition from the ROC to the PRC. Since 2001, 14 countries have don se - that’s fully half of the countries that officially recognized the ROC in 2001. And four of those were just in the last three years.
That is pretty curious behavior, to say the least, given what everyone supposedly knows about Taiwan’s status as an independent, sovereign state.
The other point is that despite the fact that “everyone knows it” and “China knows it too”, that’s not what China says it “knows.” The PRC’s official public statements have wavered over the decades between finessing Taiwan’s status and outright assertions of PRC sovereignty, but they’ve never acknowledged Taiwan’s sovereignty. Maybe I’m missing something, but “China knows” differently from what it says publicly, I can only think a few possible explanations for the mismatch, and none of them are particularly reassuring.
Maybe everyone in China is just mouthing empty pieties, and everyone is just afraid to be the first to point out that the Emperor has no clothes. The problem there is that I’m not sure there’s much practical difference between everyone being afraid to admit that Taiwan isn’t really a province of the PRC anymore and everyone actually believing that. I guess the hope there is that no one will want to be the first to suggest a war, either, but that doesn’t exactly seem like a stable situation to me.
Closely related, maybe everyone knows that Taiwan is independent, and everyone knows that everyone else knows it too, but it’s just too embarrassing to say so publicly, so everyone just pretends otherwise, while knowing that everyone else is also just pretending, to save face. The problem there is that when several generations have been raised only hearing the public message, they may not always get the message about the private understanding everyone is supposed to have. Polite fictions have a way of becoming self-evident verities.
The last possibility I can think of is that there’s some sort of filter in place, such that the decision-making elites all “know” Taiwan is independent and that there’s nothing they can or should do about that, but they feel a need to maintain a public fiction to appease the populace. There’s at least a couple of problems there. One is the problem above, that generations of public proclamations can create their own truths, and the filter may not work that well. The other is that if there is a widespread public sentiment demanding reunification with Taiwan, it may be increasingly difficult for the elites that “know better” to resist domestic pressure.
But, of course, I could be wrong about all of that. Again, I hope that I am - I don’t want to see a war over Taiwan. But I’m definitely not convinced that
