CBS News: Summit Between Trump And Kim Jong Un Will Be Held In Singapore

May 09, 2018 - 7:57 pm

WASHINGTON (WCBS 880/CBS News) -- Singapore will be the site of the planned summit between President Donald Trump and North Korean leader Kim Jong Un, CBS News has learned.

No date or time has been set.

Secretary of State Mike Pompeo was due to return from North Korea early Thursday morning, where he was building the "framework" for the Trump-Kim summit, with three now-free Americans that were being held hostage by the regime.

Pompeo and the three Americans landed back on American soil in Alaska Wednesday evening.

Former U.N. Ambassador Bill Richardson joined CBSN anchor Reena Ninan on Wednesday to discuss what may happen at the summit.

"I think in the end, total denuclearization, maybe, is long away, but it's possible. Anything is possible," Richardson, who was also Governor of New Mexico, said Wednesday. "My worry is that we have such high expectations and then the results are modest."

He expressed caution that the United States should enter the "dicey" negotiations with a clear plan. President Trump, Richardson says, needs to be fully prepared for the meeting in the face of North Korea, which will have its own agenda.

Richardson says that North Korea does not tend to make diplomatic agreements formally and advised that President Trump find some other way of building trust with North Korean leader Kim Jong Un.

"You have two very bold, unpredictable leaders that have decided to have a summit of their own," he said. "I think we have made a concession to the North Koreans by President Trump meeting with the North Koreans, but I think it's a risk worth taking."

Richardson also said it is a "familiar pattern" for North Korea to use hostages as "bargaining chips," but acknowledged it was a positive development ahead of the presidential summit.
