China has to invade Taiwan only if the US starts arming Taiwan to use it as a pawn against China like how the US openly declared that it intends doing. China will not make the mistake of waiting 8 years like Russia.
> China is strong enough that they don't have to listen.
Any sane observer of geopolitics who doesnt have a 6-figure paycheck that depends depend on saying what his employers want said, would say that China has been silent for way too long and the US would immediately start a war if anyone did so much as to threaten doing what the US has been doing to other countries. Then again, China has only recently reached the military power that could fight the US on even grounds without having to resort to a nuclear war.
