China hasn't fought a war in more than 40 years. China fought limited border wars with India many decades ago. The Sino-Vietnam war was 1979. The invasion of Tibet is the most relevant example here. Tibet was internationally recognized as part of China, but was de facto independent, similarly to Taiwan nowadays. The PRC invaded as soon as it won the civil war, because it was one of the last parts of China that was still beyond the control of the central government. However, I think it's clear that the PRC today views an invasion of Taiwan as a last resort, not as the policy of choice.
