evidence: The three-day summit began Tuesday with thousands of North Koreans lining the streets of Pyongyang to welcome South Korean President Moon Jae-in on his first trip to North Korea. [...] Pyongyang is also likely to reiterate its demand for the withdrawal of U.S. troops from the peninsula, Paal said. North Korea has repeatedly said that the U.S. military presence in South Korea poses a threat to its regime. Currently, there are about 28,500 U.S. troops stationed in South Korea. [...] At the summit, South Korean Minister of National Defense Song Young-moo and First Vice Minister of People’s Armed Forces of North Korea No Kwang Chul signed a comprehensive military agreement to halt military exercises along the military demarcation line by Nov. 1 and remove 11 guard posts in the DMZ by year’s end.
