If Trump win, there will probably much less geopolitical tension since he is not the kind of guy that is interested in geopolitics. But on business front, it will be blood bath. China really need to speed up dedollarization effort, significantly cut treasury holdings. Not only Trump has hint that he could make the US default on its debts, but more importantly, he also seem doesn't care if his policy bring the US to financially bankrupt. He could really bring the world to great depression.
