I .Trump blasts trade deals, departing from GOP orthodoxyBy JILL COLVIN and LISA LERERASSOCIATED PRESSMONESSEN, Westmoreland County — Donald Trump called for a new era of economic “Americanism” Tuesday, promising to restore millions of lost factory jobs by backing away from decades of U.S. policy that encouraged trade with other nations — a move that could undermine the country’s place as the dominant player in the global economy.The speech marked a significant break from years of Republican Party advocacy for unencumbered trade between nations, and drew immediate condemnation from GOP business leaders.In his 35-minute speech, Trump blamed former President Bill Clinton and his wife,Democratic presidential rival Hillary Clinton, for the loss of millions of manufacturing jobs.He threatened to exit the more than two-decade-old North American Free Trade Agreement and vowed to withdraw from the Trans-Pacific Partnership, an agreement among 12 Pacific Rim nations that has yet to take effect.He pointed to China as a source of many of America’s economic woes, promising to label that country a currency manipulator and slap new tariffs on America’s leading source of imports, a decision with the potential to dramatically increase the cost of consumer goods.“This wave of globalization has wiped out totally, totally our middle class,” Trump said, standing in front of pallets of recycled aluminum cans on a factory floor. “It doesn’t have to be this way. We can turn it around, and we can turn it around fast.”Delivered in a hard-hit Pennsylvania steel town, the speech underscored the central message of Trump’s campaign: that policies aimed at boosting international trade — and America’s intervention in wars and disputes abroad — have weakened the country.
