President Trump has threatened to impose a new round of tariffs on $200 billion of Chinese products, ranging from refrigerators to Apple watches. The threat of the 10 percent tariffs have alarmed Wall Street executives, including the heads of Goldman Sachs, Morgan Stanley, the Blackstone Group and others, who flew to Beijing for hastily arranged meetings, including one with China’s vice president today, to discuss strengthening business ties between the U.S. and China. Trump’s latest tariff threat may also jeopardize the planned trade talks between Treasury Secretary Steven Mnuchin and top Chinese officials later this month.
