Xi claims that they should not pass 'the problem' to the next generation. The problem however is that an invasion of Taiwan is that it would likely lead to huge sanctions against China from the West. A large portion of the Chinese economy is reliant on dumping price competitive goods in the West. This would lead to a global recession and a collapse in living standards in the West and in China. That is reason enough for the CCP to not invade Taiwan, as it is not worth it at all to gain a large island. Also there is a lot of trade/movement between Taiwan and China, there is little purpose to invading it outside of political prestige. The Chinese, like the Russians see Western civilization as a sinking/stagnating ship and the US political leadership as an unstable psychopathic mad dog especially with Trump & Biden. The Chinese call Trump "Comrade Trump" making fun of him as the secret CCP agent that would speed up the disappearance of the US from world history. Overall security threats from the US and also the stagnation of Western economies these past 20 years has forced the Chinese to heavily diversify their trade/diplomacy away from the West and more towards the other 80% of the world.
