I posted a long answer to this in the Ukraine thread that you can read here:
The problem I have is what does Putin do with the peace? How does he govern or remotely govern a huge country and stubborn population of millions that he just bombed and shot up..? That is also the issue I don't know the answer to. Unfortunately I dont think Putin had a choice with Ukraine...
Basically, China does not want to necessarily "invade" Taiwan at all.
They don't want to kill Chinese, which would happen if they invaded.
China wants all Chinese people united.
Doing so by war/violence is a last resort.
But of course, the US is pushing them in that direction now.
There is nothing Russia can do to help Chinese and Taiwanese people re-unite. This has to be solved by the Chinese people in the two countries. Just as Korean unification will need to be solved by the Koreans. The US, in both cases, is being an obstacle to reunification.
If you look at the Ukraine situation, it's very similar in that the Slavic peoples there just wanted Slavic people to cooperate. After the Maidan coup, when a foreign puppet anti-Slavic government was installed in Ukraine, Russia tried for 6 years to make things work, but finally the US pushed them into a corner and when America threatened Russian security, they resorted to violence to re-unite the Slavs under pro-Slavic government. China is not (yet) being pushed into a corner like Russia was, so it is extremely unlikely they will resort to a forced takeover.
China could have forcefully taken over Taiwan during most of the past 70 years. Ability or inability to invade has essentially nothing to do with their plans for reuniting Taiwan. There are a handful of places like this around the world--Northern Ireland being a glaring example--a larger country could roll in tanks and take over the pseudo-state, but that would be detrimental to both sides so they don't do it.
Also, there is no reason to take over Taiwan if it means Taiwan's computer hardware production (ie "chips") is going to be offline for a considerable amount of time. Taiwan makes a lot more than chips though. Almost every computer motherboard is manufactured there, and they used to produce ALL lcd screens. It's way more than just chips.
There is not going to be any Taiwanese takeover that risks computer hardware production. China values the 20m Chinese people living in Taiwan, but it also really values Taiwanese industry as well.
