Donald Trump becomes the first sitting US President to visit the Democratic People's Republic of Korea (North Korea).

Donald John Trump is an American politician, media personality, and businessman who is the 47th president of the United States. A member of the Republican Party, he served as the 45th president from 2017 to 2021.

The 2019 Koreas–United States DMZ Summit was a one-day summit held at the Korean Demilitarized Zone between North Korean chairman Kim Jong Un, U.S. president Donald Trump, and South Korean president Moon Jae-in, following the 2019 G20 Osaka summit. Trump briefly stepped over the border at 3:45 PM (GMT+9) on June 30, marking the first time a sitting U.S. president had set foot on North Korean soil. It was also the second time since the end of the Korean War in 1953 that a North Korean leader entered the South's territory, following the April 2018 inter-Korean summit. Senior White House advisors Ivanka Trump and Jared Kushner also attended the summit, with Ivanka Trump and U.S. envoy to South Korea Harry B. Harris Jr. holding a meeting with Kim later broadcast on North Korean television.

North Korea, officially the Democratic People's Republic of Korea (DPRK), is a country in East Asia. It constitutes the northern half of the Korean Peninsula and borders China and Russia to the north at the Yalu (Amnok) and Tumen rivers, and South Korea to the south at the Korean Demilitarized Zone (DMZ). The country's western border is formed by the Yellow Sea, while its eastern border is defined by the Sea of Japan. North Korea, like South Korea, claims to be the sole legitimate government of the entire peninsula and adjacent islands. Pyongyang is the capital and largest city.

June 30 is the 181st day of the year in the Gregorian calendar; 184 days remain until the end of the year.
