By Emily Green, Jarrett Renshaw and David Ljunggren MEXICO CITY/WASHINGTON/OTTAWA (Reuters) -Mexican and Canadian officials are increasingly frustrated by tariff negotiations with the Trump administration,

Global markets fell after steep U.S. tariffs on China, Canada and Mexico went into effect, and as the possible ramifications of a global trade war set in.

President Trump suspended tariffs for both countries after Mexico’s leader presented her security successes, and after U.S. markets fell and business leaders urged the White House to change course.

“Your government has chosen to put American jobs at risk at the thousands of workplaces that succeed because of materials from Canada, or because of consumers in Canada, or both,” Trudeau said, further warning of rising prices on groceries, gas, cars, and homes.

President Trump's sweeping tariffs threatened to upend free trade in North America and sent shock waves through the global supply chain.

Mexico's government may look for other trade partners, the nation's president said on Wednesday, after the United States slapped tariffs on its southern neighbor.

As Canada and Mexico make plans for reciprocal tariffs on U.S. goods, Canadian Prime Minister Justin Trudeau calls President Trump's move "a very dumb thing to do."
