If the u. s. dollar is strong, what is the impact on trade between china and the u. s.?

Moreover, the strong Dollar can buy more commodity from China because the U.S will have to pay for the commodity. Thus, import in the U.S. will increase. But, importing commodity by china from the U.S is costlier. Thus, import in China will fall.
