China is a nuclear power with the world’s largest army and a population of over 1.3 billion. It boasts the world’s second-largest economy, and is the largest single foreign owner of U.S. public debt. Its Communist Party regime, in place since 1949, now serves as a model for authoritarian states around the globe. And it may well be heading toward a major economic and political crisis. Yet for some reason, the U.S. presidential candidates have barely mentioned China in nearly a year of campaigning. When they do, the discussion tends to focus on pressing matters such as the price of imported tires.
