Putin hails ‘unshakable foundations’ in meeting with China’s Xi

sway over a strategically vital yet deeply unpredictable partner.China wants stability on its border and influence in Pyongyang, but without being dragged into crises triggered by North Korea's nuclear ambitions. So Xi's visit this week - he arrived in Pyongyang on Monday -

is likely to be less about friendship, more about leverage. Seoul believes he may try to position China as a mediator between North Korea and the United States, but Beijing may have other motives.Western diplomatic sources tell the BBC that China has become increasingly concerned about the growing partnership between Pyongyang and Moscow. After meeting Russian leader Vladimir Putin last week, Xi may want to ensure he also keeps North Korean leader Kim Jong Un in check, especially as Beijing increases its presence on the global stage.A thaw in strained tiesThe cooling between Beijing and Pyongyang was visible, even if subtle. They barely marked the 75th anniversary of diplomatic relations in October 2024. Public messaging was muted. China's ambassador did not attend North Korea's founding celebrations the previous month. There were no senior level exchanges throughout the year, a stark contrast with Pyongyang's increasingly warm relationship with Moscow.That growing closeness with Russia has unsettled Beijing. After Russia's invasion of Ukraine, North Korea has expanded military cooperation with Putin, culminating in a mutual defence pact that was signed during Putin's visit to Pyongyang in 2024. About 2,300 North Korean soldiers have died fighting for Russia against Ukraine, according to a BBC investigation. Pyongyang is also accused of supplying ammunition for Russia's war effort in exchange for oil and aid, a development that has alarmed Washington and its allies, and quietly rattled China."China wants to ensure that its interests vis-a-vis North Korea are protected at a time of rapid convergence between Moscow and Pyongyang," adds Ankit Panda, a nuclear policy specialist at the Carnegie Endowment for International Peace.AFP via Getty ImagesCut off from the world, North Korea's dictatorship relies heavily on China and Russia China has only one formal defence treaty, and that is with North Korea. So Beijing is unlikely to welcome a scenario where Russia becomes the dominant influence in Pyongyang. A more confident, less dependent Kim would mean reduced Chinese leverage.Beijing has responded by trying to reset the relationship. Late last year, Xi invited Kim to a military parade in Beijing, keeping him prominently by his side alongside Putin. It was their first formal summit in six years. Xi praised the two as "good neighbours, good friends and good comrades bound by a shared destiny", and called for closer strategic coordination. Notably absent from the public statements was any mention of North Korea's nuclear arsenal.Beijing has "mixed feelings" about the growing partnership between Pyongyang and Moscow, says Lee Seong-hyon, a visiting scholar at the Harvard University Asia Center.On one hand, the partnership "distracts Washington and complicates US strategy in multiple theaters, which indirectly benefits China", Lee says.But, he adds, expanding military cooperation between Russia and North Korea could spark a stronger trilateral military response from the US, Japan and South Korea, which would worry Beijing.That is also why China is not endorsing Pyongyang's nuclear programme - because that would increase US involvement in the region and its alliances here.

But neither is China confronting t
