That won't happen, world powers may dump China and move production out of China if they are found of deliberately inflicting this pains on the whole world to gain economic dominance. You can't use virus that kills thousands and shutdown economy and people to dominate the world space. The people should violently react or they are docile.
What if this virus is not proven produce by China? the thing is some countries are assuming that it was China who created the virus but they cannot prove it, all of what they are saying is based on speculation only. So let us look the world now, which country is standing tall? I see China for now, and no evidence they can't sanction China.
