The Kim–Xi meetings were a series of summits between North Korea and China during 2018 and 2019. North Korean supreme leader Kim Jong Un secretly met with Chinese paramount leader Xi Jinping on March 25–28, 2018. Xi made a classified invitation to Kim to visit China, after which Kim visited Beijing and used his bullet proof train to travel to the three-day meeting. It is his first known out-of-country diplomatic trip since taking power. Kim and Xi had a second surprise meeting on May 7–8, 2018 in the city of Dalian. Kim and Xi had a third surprise meeting on June 19–20, 2018. They had a fourth surprise meeting on January 7–10, 2019 in Beijing, followed by a fifth official DPRK and China summit June 20–21, 2019 in the Forbidden City, Pyongyang.

The bilateral relations between the People's Republic of China (PRC) and the Democratic People's Republic of Korea (DPRK) have been generally friendly, although they have been somewhat strained in recent years because of North Korea's nuclear program. They have a close special relationship and China is often considered to be North Korea's closest ally. China and North Korea have a mutual aid and co-operation treaty, signed in 1961, which is currently the only defense treaty either country has with any nation.
