One thing is absolutely certain whether Trump realizes it or not.... China will never bargain away Taiwan, no matter what threats Trump makes. 
Trump has absolutely no realistic  leverage to apply. Boycott Chinese goods or impose tariffs? China will simply find new emerging markets in places like India, African countries, and South America. And if not, they'll simply suck up the losses. It's not like their government is accountable to the people so there will be no political pressure. And in the meantime, American consumers will find that the things they buy regularly will suddenly become unaffordable. Add to that the loss of jobs in retail as businesses go broke because their customers can no longer afford to buy their wares and Trump's promise to create jobs falls flat. 
China, like it or not, is not a country that can be bullied.
