Xi Jinping’s North Korea visit and silence mark shift in nuclear diplomacy

Chinese President Xi Jinping travelled to Pyongyang for the first time since 2019, using the trip to bolster his domestic standing ahead of a possible fourth term and to reaffirm China’s influence over North Korea. The visit highlighted Beijing’s desire to keep Pyongyang aligned with Chinese interests while warning against an over‑reliance on Moscow.

Soon after, Xi remained silent on North Korea’s declared “irreversible” nuclear status, breaking a decade‑long pattern of diplomatic engagement. Analysts describe the silence as a strategic decoupling, signalling that China will no longer shield Pyongyang from the fallout of its expanding nuclear arsenal, which now contains an estimated 40‑60 warheads and has seen three underground tests since January 2026. The shift has prompted South Korea and Japan to accelerate defensive deployments and has raised concerns about a regional arms race. Beijing has also begun secondary sanctions on North Korean trade routes through Dalian and Dandong, threatening Chinese manufacturers that rely on Korean coal and rare‑earth exports and adding further complexity to supply chains linked to South Korean semiconductor producers.
