North Korea has made official mention for the first time of a planned summit between leader Kim Jong Un and U.S. President Donald Trump, telling visiting Secretary of State Mike Pompeo that it would be a "historic" opportunity, state media said Thursday.

Pompeo visited Pyongyang a day earlier to discuss with the North Korean leadership planning for the summit, which will focus on the country's nuclear weapons program. Media reports have said it is likely to take place in mid-June in Singapore.

Kim, who has conducted a flurry of diplomatic moves in recent weeks, said his summit with Trump "would be a historic meeting" and an "excellent first step" toward the "building of a good future" on the Korean Peninsula, according to the North's official Korean Central News Agency.
