China may appear an economic and military powerhouse but it is confronting critical challenges at home. Environmental pollution—especially of the air—is not only hugely unpopular and economically costly; it is a killer, responsible for the deaths of a staggering million to a million and a half Chinese annually.
China also faces a looming demographic crisis with its aging population, shrinking workforce, and huge number of people who will retire with only a single child and a drastically inadequate social safety net to support them. The cost of pensions and health care will balloon. Anticipating the coming cliff, Beijing changed its one-child policy to a two-child policy in late 2015, producing a small increase in births but not yet what is hoped for. Stalled economic reform also belongs on this list of weaknesses, as does widening inequality and continuing deep poverty in rural areas.
