May 6 (Reuters) - Canada's main stock index on Monday hit its lowest level in nearly a month after U.S. President Donald Trump threatened to raise tariffs on China, triggering a global rout in risky assets.
* At 10:13 a.m. ET (14:13 GMT), the Toronto Stock Exchange's S&P/TSX composite index .GSPTSE was down 101.46 points, or 0.62 percent, at 16,392.97.
* Trump said on Sunday said he would hike U.S. tariffs on $200 billion worth of Chinese goods this week, marking a major escalation in tensions between the world's largest economies and quashing investor hopes of a trade deal that has sparked a rally in risk assets this year. Canada is leaning on the United States to help settle the dispute with China, which has started to block imports of vital Canadian commodities amid a dispute over a detained Huawei executive. The Canadian dollar weakened to a 10-day low against its U.S. counterpart and oil prices took a hit from the ongoing worries about trade. O/R
