Chinese President Xi Jinping begins a two-day state visit to North Korea Monday, coinciding with the 65th anniversary of the Sino-North Korean friendship treaty. The summit is expected to focus on restoring bilateral ties and expanding economic and security cooperation.

Ahead of the visit, North Korea has intensified its display of nuclear capabilities. After inspecting nuclear material production facilities, North Korean leader Kim Jong-un continued a series of public appearances highlighting the country’s nuclear and missile programs. On Sunday, his sister, Kim Yo-jong, declared that North Korea’s status as a nuclear weapons state was “an irreversible red line.”

She also rejected reports that Beijing and Washington had reaffirmed their support for the denuclearization of the Korean Peninsula during last month’s U.S.-China summit, calling them “fabricated” and “groundless.” The message appeared aimed not only at the United States but also at China, signaling that denuclearization is no longer open for discussion.
