In a confrontation, America could restrict its own food exports to China, which have rebounded since a truce of sorts was reached, and lean on other big suppliers such as Argentina and Brazil to do likewise. It could try to influence countries that sell metals to China, including Australia and Chile. And most of China’s commodity imports are shipped through a few straits and canals that America could seek to block for Chinese vessels by, say, posting military ships nearby.
