The results of the US-North Korea summit in Singapore earlier this month have surpassed all expectations, South Korean President Moon Jae-in said on Wednesday ahead of his visit to Russia.

"The results of the summit turned out to be impressive," the South Korean leader said in his interview to reporters.

"The North Korean-US standoff has lasted for 70 years. Now it’s the time for those two nations to renounce hostility. A new historic moment, when we can establish the system of solid peace in the region, opens before us," he said, adding that the results of the summit have surpassed all expectations.
