You’re confusing the faction leading the country with the people themselves.

South Korea and Taiwan as countries don’t have an inherent will to align with the West. The countries are made up people with different beliefs, some are more aligned to democracy (what you call the West) and some aren’t. Even today Taiwan has a political party that is pro-CCP.

The logic is not that the CCP will suddenly want to align with the West, it’s that the people will become more pro-Democratic as they become more developed (both economically and politically).
