The China-US trade conflict is taking a more severe turn. President Trump announced a 10 percent tariff on an additional $300 billion of Chinese imports; the Chinese government responded by allowing its currency, the yuan, to fall to more than 7 to the dollar—the lowest in a decade. The US government then formally labeled China a “currency manipulator,” which carries no formal penalty but sets in motion a process that might lead to sanctions by the International Monetary Fund.
