China Reaffirms "Unshakable" Bond With North Korea as 65-Year Defense Pact Reaches Milestone

Leaders Exchange Letters as Treaty Turns 65

Chinese President Xi Jinping said China's commitment to its "traditional friendship" with North Korea would hold steady no matter how global politics shift. The message came in a letter to North Korean leader Kim Jong Un, published Saturday by North Korea's state news agency KCNA.

Kim replied that ties between the two countries had reached a "new strategic level." The letters were timed to the 65th anniversary of the Treaty of Friendship, Cooperation and Mutual Assistance, signed on July 11, 1961. It remains Beijing's only active mutual defense agreement with any country.

Xi was quoted describing the relationship in sweeping terms, pledging continued backing for what he called North Korea's "socialist cause" under Kim's leadership and for a "favorable strategic environment" for both governments.

A Delegation in Beijing, a Summit Still Fresh

North Korea's Premier Pak Thae Song arrived in Beijing on Friday for a three-day visit, leading a party and government delegation invited by the Chinese Communist Party. Pak was received at the Great Hall of the People and laid a wreath at the Monument to the People's Heroes on Tiananmen Square — the first such gesture by a senior North Korean official in seven years.

The visit follows a bigger event just a month earlier: Xi's own trip to Pyongyang in June, his first there since 2019 and his only foreign trip so far this year. During that visit, Xi and Kim agreed to widen cooperation across politics, the economy and culture, language both governments have since repeated in public statements.

China's foreign ministry described the relationship as a "steadfast strategic policy," while state broadcaster CCTV reported that Xi told Pak the June summit had given "strategic guidance" for deepening ties.

Why the Treaty Still Matters

The 1961 treaty was signed by North Korea's founder Kim Il Sung and then-Chinese premier Zhou Enlai. Its defining feature is a clause committing each side to military assistance if the other is attacked — a Cold War-era guarantee that has never formally been triggered but still underpins Beijing's only binding defense commitment to another state.

For decades, the alliance functioned more as a historical formality than an active partnership, particularly as Beijing balanced its ties to Pyongyang against relations with Washington and Seoul. That calculation appears to be shifting. Since late 2025, the two countries have resumed direct flights and passenger train service between their capitals and stepped up diplomatic contact, according to Reuters reporting.

North Korea's government is one of the most closed and tightly controlled in the world, and its human rights record — including forced labor and political imprisonment documented over the years by the United Nations — has drawn wide international criticism. China's Communist Party, for its part, has faced its own long-running scrutiny over human rights, from its treatment of religious and ethnic minorities to its suppression of political dissent at home. The renewed warmth between the two governments is a reminder that the relationship is built on shared political systems as much as strategic convenience.

What Comes Next

Analysts see the flurry of exchanges — Xi's June visit, Pak's Beijing trip, and now the anniversary letters — as evidence that Beijing and Pyongyang are moving from symbolic gestures toward a more functioning strategic partnership. South Korea's unification ministry said it is "closely monitoring" developments, noting this is the first time in seven years that North Korea has sent a delegation to Beijing for the treaty anniversary.

The warming comes as Washington continues to enforce sanctions aimed at curbing North Korea's weapons programs, and as the Trump administration keeps a close watch on Beijing's role in propping up the Kim regime economically and diplomatically. Whether the renewed alliance translates into concrete shifts — expanded trade, deeper military coordination, or further high-level summits — is likely to become clearer in the months ahead.
