There is a great deal of volatility in foreign-exchange markets across the globe, mainly owing to the weakening of the dollar. As such, China and other countries are holding a depreciating asset that should be managed to serve domestic interests rather than those of the US.
这就是中国维持包括固定汇率在内的当前政策所要付出的高额代价。全球的外汇市场瞬息万变，主要是因为美元的疲软。中国和其他国家手里握着的是一笔不断贬值的财产。这笔财产应该用来实现本国的利益，而不是美国的利益。
