...except threatening Taiwan with war? And ask the people in Tibet and (some) in Hongkong.
Can you name a sovereign state recognized globally that is being threatened by China militarily?
Yes there is historical resentment, but people in our generation are rational, peace-seeking and pragmatic.
Case closed?
The only reason why China hasn't rolled tanks into Taiwan is because of logistical or political inconvenience, otherwise China could treat Taiwan just the same as Tibet.
