U.S. Republican presidential candidate Donald Trump said on Tuesday, May 17 he is willing to talk to North Korean leader Kim Jong Un to try to stop Pyongyang's nuclear program, proposing a major shift in U.S. policy toward the isolated nation, Reuters reports.

In a wide-ranging interview with Reuters, Trump also called for a renegotiation of the Paris climate accord, said he disapproved of Russian President Vladimir Putin's actions in eastern Ukraine, and said he would seek to dismantle most of the U.S. Dodd-Frank financial regulations if he is elected president.

The presumptive Republican nominee declined to share details of his plans to deal with North Korea, but said he was open to talking to its leader.

Trump, 69, also said he would press China, Pyongyang's only major diplomatic and economic supporter, to help find a solution.

On Russia, Trump tempered past praise of Putin, saying the nice comments the Russian leader has made about him in the past would only go so far.

Trump said he is "not a big fan" of the Paris climate accord, which prescribes reductions in carbon emissions by more than 170 countries. He said he would want to renegotiate the deal because it treats the United States unfairly and gives favorable treatment to countries like China.

Trump has been criticized for offering far fewer specific policy proposals than Clinton, his likely rival for the Nov. 8 presidential election.

The New York billionaire said he planned to release a detailed policy platform in two weeks that would propose dismantling nearly all of Dodd-Frank, a package of financial reforms put in place after the 2007-2009 financial crisis.
