Donald Trump needs unfamiliar tools like patience for North Korea talks

US President Could Bumble Way to Korean Rebalancing

White House press secretary Sarah Sanders on Friday said North Korea must prove "concrete and verifiable actions" ahead of any meeting with President Trump, declining to commit to any specific date for such a gathering to take place.

South Korea's National Security Office head Chung Eui-yong told reporters at the White House on Thursday after briefing Trump that Kim had "committed to denuclearisation" and to suspending nuclear and missile tests.

"Well I think it's really clear they misplayed it, or we wouldn't be in the position that we're in", Sanders said.

Sanders said Trump won't have the meeting "until we see concrete actions that match the words and the rhetoric of North Korea".

President Donald Trump will need to adopt an unfamiliar set of traits - patience, persistence, clear goals and conditions - and be prepared to walk away when he meets North Korean leader Kim Jong Un, people who have negotiated with Kim's regime say.

The world, long used to the verbal duel between the US President Donald Trump and the Korean Dictator Kim Jong, has been taken aback by the developments.

Former senior State Department official Evans Revere, who has experience of negotiating with North Korea, warned there could be a disconnect between how the two parties describe denuclearisation.

Instead, Kim only promised to stop nuclear and ballistic missile testing and said he accepted the right of the US and South Korea to move forward with joint military exercises later this year.

However, she added that the meeting of Trump with Kim Jong-un would be impossible in case North Korea does not take definite steps toward the cancellation of its nuclear program.

"It's a risky strategy", Bremmer said, with a "greater chance of breakthrough but also greater chance of war - and also one that the Trump administration isn't well-staffed to execute on".

Sanders reiterated that the Trump administration will continue with its "maximum pressure" campaign on Pyongyang.

Clinton's words echo those of veteran diplomat and former U.S. ambassador to the United Nations, Bill Richardson, who warned that negotiating with North Korea was not "reality television".

"I would say this: The most important thing right now is to keep those sanctions on, keep the pressure on, as we go into these negotiations".

"North Korea seemed to be holding back their last concession so that they could get the big visit and the Clinton administration knew that the visit was the big deliverable and they wanted to spend it very carefully", he said. "A summit is a reward to North Korea", said Robert Kelly, a professor at South Korea's Pusan National University.

It's likely North Korea will demand US military concessions.

North Korean dictators have played USA leaders for decades, with the West sending the Hermit Kingdom billions of dollars in humanitarian and financial aid, while it developed the nuclear weapons it now uses to threaten us.

"China will welcome the dialogue between the US and North Korea, and resolutely support North Korea securing its due interests in the process of denuclearization".

"Trump's record of cosying up to authoritarian governments, his consistent failure to appoint, empower or value the expertise of professional diplomats, and his overall lack of focus on critical details also give me pause. But I commend him for his very bold move in accepting the invitation", Richardson told AFP on Friday.

Instead, North Korea is understood to have agreed to halt its testing programme as negotiations continue.

But on Friday the Washington Post reported a statement from the North Korean ambassador to the United Nations in NY, who credited the developments to the "great courageous decision of our Supreme Leader". Traveling to North Korea risks conferring legitimacy on Kim and his country.
