President Trump claimed on Sunday his administration made "progress" this weekend on diplomatic efforts to denuclearize North Korea.

In a tweet, the president said he plans to meet again soon with the country’s leader, Kim Jong Un, after Secretary of State Mike Pompeo had a "good meeting" in Pyongyang.

“[Pompeo] had a good meeting with Chairman Kim today in Pyongyang,” Trump said. “Progress made on Singapore Summit Agreements! I look forward to seeing Chairman Kim again, in the near future.”

Pompeo met with Kim for two hours in North Korea seeking to reignite stalled negotiations on the terms of denuclearizing North Korea, after the two sides made vague commitments during June's Singapore summit where Kim and Trump met for the first time.

The office of South Korea’s President Moon Jae-in, which has helped facilitate dialogue between the U.S. and North Korea, said the U.S. and North have agreed to hold a new summit meeting. “It’s a very nice day that promises a good future for both countries,” Kim said through an interpreter during the meeting, the New York Times reports.

“We had a great, great visit this morning. President Trump sends his regards," Pompeo said in reply. "And we had a very successful morning, so thank you."

Pompeo later posted a photo of himself with Kim on his Twitter account.
