South Korean media recently reported that Chinese security and protocol personnel have already arrived in Pyongyang to make preparations, and that Chinese President Xi Jinping may visit North Korea in late May or early June.

China hasn’t yet confirmed the trip, but a visit is both overdue and, from Xi’s perspective, necessary. As close as Beijing and Pyongyang are on paper, relations between the two behind the scenes are often tense; China has never quite accepted North Korea’s status as a nuclear power and worries about losing influence in the country to Russia.

Xi last paid a state visit to Pyongyang in June 2019, nearly seven years ago. Even after deducting the three years of the pandemic, that’s a long delay, and in that time Xi has visited many countries—including South Korea. Even more foreign leaders have come to China, ranging from Cuban and Venezuelan leaders to, in the last few weeks, U.S. President Donald Trump and Russian President Vladimir Putin. There have been a fair number of visitors to Pyongyang, too, from Putin to Vietnam’s To Lam.
