A new report from British defence analysts has ignited debate by questioning the stability of the partnership between Beijing and Moscow. The assessment, titled 'A House Built on Sand?', argues that the Sino-Russian alignment is less an ideological marriage and more a transactional accommodation driven by shared antipathy toward the West. While both nations have deepened economic and military ties since 2014, analysts warn that underlying frictions over resource competition, demographic decline, and long-term strategic goals could fracture the alliance.
The report, published by the Royal United Services Institute (RUSI), highlights that the relationship is not rooted in mutual trust but in a pragmatic response to sanctions and NATO expansion. Russia increasingly depends on Chinese markets for energy exports, but tensions persist over pricing and infrastructure. For example, the Power of Siberia gas pipeline remains China's primary energy link, yet Moscow has struggled to secure favourable terms for future projects. Meanwhile, Beijing views Russia as a junior partner in a multipolar world, a role that rankles Russian pride.
Military cooperation has grown, with joint exercises and arms sales, but here too cracks appear. Russia fears that China is reverse-engineering its military technology, particularly in hypersonic weapons and engines. RUSI notes that Russian defence exports to China have declined as Beijing develops its own capabilities. In the Arctic, where both nations vie for influence, competition over shipping lanes and mineral rights could sour relations.
Demographic trends add a long-term strain. Russia's population is in steep decline, while China faces its own aging crisis. Neither can sustain the labour force needed for ambitious infrastructure or military ambitions. The report argues that as both nations pivot inward, their capacity to project power jointly will diminish.
The analysts also question the durability of their digital alignment. Russia's aggressive internet sovereignty model clashes with China's governance. Beijing has been wary of adopting Russian cybersecurity tools, preferring its own ecosystem. On quantum computing and AI ethics, the two have diverged; China invests heavily in state-controlled AI, while Russia lags, focusing on low-cost conventional technologies.
Despite these tensions, the partnership will likely endure for the near term. Both leaders benefit domestically from the narrative of resisting a US-led order. However, the report warns that a black swan event, such as a succession crisis in either country or a major economic shock, could fracture the alliance. As one analyst put it, 'They are dancing together because the music is loud, but neither knows the steps.'
The assessment serves as a stark reminder that what holds China and Russia together may be no more than a mutual disdain for the West. The question remains: how long can a house built on sand withstand the storm?
