long-term, sound and stable development of the socialist cause
In the quiet language of anniversary messages and state visits, China and North Korea are signaling something louder than ceremony: a deliberate, ideologically grounded commitment to stand together against the pressures of a world that has largely turned away from them. Xi Jinping's pledge of 'long-term and stable' ties to Kim Jong-un — offered in response to Kim's congratulations on the Chinese Communist Party's 105th founding anniversary — arrives just weeks after Xi's first visit to Pyongyang in seven years, and days before the two nations mark six and a half decades of their mutual defense treaty. What unfolds here is not merely diplomacy, but the careful tending of an alliance that both capitals understand to be a strategic necessity.
- Two nuclear-armed, sanctions-pressured states are actively reinforcing their partnership at a moment when regional tensions show no sign of easing.
- Xi's personal journey to Pyongyang in June — his first in seven years — broke a long silence and signaled that Beijing considers the relationship too important to manage from a distance.
- The repetition of 'long-term and stable' in Xi's formal message is not accidental; it is a deliberate projection of durability aimed as much at outside observers as at Pyongyang.
- The 65th anniversary of the 1961 mutual defense treaty on July 11 gives both governments a symbolic anchor around which to cluster these gestures of solidarity.
- The ideological framing — two Marxist parties, one shared socialist cause — suggests Beijing and Pyongyang are not merely allies of convenience but are constructing a shared narrative of resistance to Western-led international order.
When Kim Jong-un sent Xi Jinping congratulations on the 105th anniversary of the Chinese Communist Party's founding, the gesture was diplomatic courtesy. What Xi sent back was something more deliberate: a formal pledge that Beijing would work to ensure the 'long-term, sound and stable development' of ties between the two nations — language repeated with enough insistence to make clear it was meant to be heard beyond Pyongyang.
Xi framed the relationship in explicitly ideological terms, noting that both the Korean Workers' Party and the Chinese Communist Party are Marxist governing institutions sharing a common philosophical foundation. In a world where both countries face significant isolation from Western powers, that framing carries strategic as well as symbolic weight.
The message did not arrive in a vacuum. Just weeks earlier, Xi had made his first state visit to Pyongyang in seven years — a journey that, by virtue of being made in person rather than through envoys, communicated the seriousness with which Beijing regards the partnership. During those two days in June, the two leaders agreed to deepen cooperation and strengthen high-level communication channels.
Now, with July 11 approaching — the 65th anniversary of the Treaty of Friendship, Cooperation and Mutual Assistance that has anchored the alliance since 1961 — the convergence of these diplomatic signals appears carefully orchestrated. Anniversary visit, formal pledge, treaty milestone: together they project an image of an alliance that is not drifting, but consolidating, at a moment when both capitals have every reason to want the world to believe so.
Chinese President Xi Jinping sent a message to North Korean leader Kim Jong-un this past weekend, pledging that Beijing would work to sustain what he called the "long-term and stable" development of ties between the two countries. The exchange was reported by North Korea's state media on Sunday, and it came as a response to Kim's own message congratulating Xi on the 105th anniversary of the founding of the Chinese Communist Party on July 1.
In his reply, Xi expressed his thanks to Kim for the gesture. He framed the relationship between the two nations in ideological terms, noting that both the North Korean Workers' Party and China's Communist Party operate as Marxist governing institutions. The language suggested a shared philosophical foundation undergirding the diplomatic relationship—a framing that carries particular weight given the geopolitical isolation both countries face from much of the Western world.
The substance of Xi's message centered on a commitment to deepen the bilateral relationship. "I am ready to lead the China-DPRK relations to a long-term, sound and stable development and thus promote the stable and long-term development of the socialist cause of the two countries," the message stated, according to North Korea's official Korean Central News Agency. The repetition of the phrase "long-term and stable" underscored the durability Beijing is signaling it wants to project in the partnership.
This exchange arrives in the wake of Xi's state visit to Pyongyang on June 8 and 9—his first trip to North Korea in seven years. During those two days, the two leaders agreed to deepen cooperation between their nations and to strengthen the channels of high-level communication that allow them to coordinate policy. Such visits carry symbolic weight in diplomacy; the fact that Xi made the journey himself, rather than sending an emissary, conveyed the priority China places on the relationship.
The timing of these messages is also significant. On July 11, China and North Korea will mark the 65th anniversary of the signing of their Treaty of Friendship, Cooperation and Mutual Assistance—the mutual defense pact that has anchored their alliance since 1961. The convergence of these diplomatic gestures—the anniversary message, Xi's recent visit, and now this formal pledge—suggests a deliberate effort by both capitals to project continuity and commitment at a moment when regional tensions remain elevated and both nations face external pressure.

La Conversación del Hearth Otra perspectiva de la historia
Why does Xi feel the need to emphasize "long-term and stable" twice in the same sentence? Is that just diplomatic boilerplate, or is something specific being signaled here?
It's both. Yes, it's formal language, but the repetition matters. When you say it twice, you're not just making a promise—you're trying to convince your own audience and the other side that this isn't transactional or temporary. In a region where alliances can shift, that redundancy is a form of reassurance.
Reassurance to whom, exactly? Kim, or Beijing's own people?
Both, really. Kim needs to know China won't abandon North Korea if international pressure intensifies. And Beijing's domestic audience needs to see that the leadership has a stable, coherent strategy in the region. The message serves multiple rooms at once.
The fact that Xi visited Pyongyang for the first time in seven years—what does that gap tell us?
It tells you that the relationship had cooled or become more distant. Seven years is a long time in diplomacy. The visit itself was a recalibration, a signal that Beijing wanted to reset the tone and intensity of engagement. This message is the follow-up to that reset.
And the treaty anniversary on July 11—is that just a calendar coincidence, or is it orchestrated?
Nothing about this timing is accidental. You don't send these messages days before a major anniversary by chance. It's choreography. Both sides are building a narrative of continuity and commitment heading into that date.
What happens if the relationship destabilizes again after July 11?
Then you'll know the pledges were more about managing the moment than about genuine structural change. But for now, both leaders are betting that showing unity serves their interests better than showing distance.
