川普将能源问题纳入竞选辩论

Presumptive Republican presidential candidate Donald Trump on Thursday pledged to cancel the Paris climate agreement and aggressively pursue U.S. fossil fuel development, during a speech at a petroleum conference in North Dakota.

He attacked Democratic frontrunner Hillary Clinton's positions on energy policy, drawing sharp contrasts between the two on an issue that could be a factor in the general election.

He said President Barack Obama has "made life much more difficult for North Dakota." And under Clinton, he said, "things will get much worse."

In his first 100 days in office, Trump said, he would roll back regulations on drilling, "cancel the Paris climate agreement and stop all payments to U.N. global warming programs."

Environmentalists condemned the speech.
