Russia May Be Helping China Prepare for War Over Taiwan, Report Says

Russia’s costly war in Ukraine may be generating a second-order threat: according to a new report from The Economist, Moscow may be sharing battlefield lessons with Beijing — intelligence that could materially advance China’s preparations for military action against Taiwan.

The report, covered by UA.NEWS on Thursday, adds a significant dimension to the already deepening partnership between Russia and China, two powers that declared a friendship with “no limits” just days before Russia launched its full-scale invasion of Ukraine in February 2022.

A War That Teaches

Russia’s military has paid a severe price in Ukraine. A Trump administration aide told The Independent this week that Russian forces are losing approximately 5,000 troops per week — a figure that, if accurate, would represent one of the heaviest sustained casualty rates in any conflict since World War II.

Yet wars of this scale also produce intelligence at scale. Russia has amassed real-world operational data on drone warfare, electronic jamming, missile interdiction, Western air defense systems, and the logistics of sustaining a large-scale ground campaign against a Western-armed opponent. Every lesson learned — and every weakness exposed — is potentially transferable.

For China’s People’s Liberation Army, which has not fought a major war since 1979, access to that data would be operationally significant.

The Logic of the Exchange

The Economist’s analysis suggests the Russia-China relationship may have moved beyond economic lifeline into active military coordination. The structural incentives are not difficult to identify.

Russia benefits from a stronger, more confident China. A Beijing that feels operationally ready for a Taiwan scenario keeps American strategic attention divided — between the Pacific, the Middle East, and Eastern Europe simultaneously. That division reduces Washington’s capacity to escalate pressure on Moscow.

China, for its part, has watched the Ukraine war closely. The PLA has reportedly studied how Ukraine’s Western-supplied air defense systems performed against Russian missile salvos, how drone swarms disrupted conventional logistics, and how satellite communications — particularly Starlink — became a decisive battlefield tool. If Russia is now providing direct technical assessments, the PLA’s planning confidence could increase significantly.

Taiwan’s Exposure

Any transfer of hard-won Ukrainian battlefield experience poses direct implications for Taiwan. The island’s defense rests in large part on deterrence by denial: making a cross-strait amphibious assault too costly for the PLA to sustain. Lessons about suppressing air defenses, neutralizing logistics networks, or degrading command-and-control could give Chinese planners a clearer picture of what a Taiwan operation would actually cost — and what it would require to succeed.

Recent data suggested PLA sorties in the Taiwan Strait had fallen to a three-year low, an indication that Beijing may be deliberately managing escalation optics. That restraint in visible signaling, combined with intensified behind-the-scenes preparation, would be consistent with a long-horizon strategy.

Washington’s Bandwidth Problem

The potential Russia-China military nexus arrives at a moment of acute U.S. strategic overextension. American strikes on Iranian infrastructure entered their thirteenth night this week, and diplomats are simultaneously attempting to construct an Iran settlement while managing Russia-Ukraine ceasefire talks.

On the defense modernization front, the Pentagon announced a nearly $7 billion contract with Oracle to unify defense software across commands and reduce costs by $441 million — a signal that Washington is investing in the digital backbone needed to coordinate multi-theater operations. But software integration does not translate immediately into operational bandwidth.

The convergence of simultaneous pressure points — an active Middle East campaign, a stalemated European war, and an assertive China absorbing Russian military intelligence — is a combination that no post-Cold War American administration has faced.

What Remains Unknown

The Economist’s framing — “may be helping” — reflects genuine analytical uncertainty. The specific nature of any Russian assistance to China is not publicly established. Whether coordination involves formal intelligence-sharing agreements, technical officer exchanges, joint wargaming, or informal channels is unknown.

What is established is the pattern: Russia and China have expanded military and diplomatic coordination throughout the Ukraine conflict, with Moscow also deepening ties with Pyongyang. A three-way alignment among Russia, China, and North Korea — each sharing lessons and capabilities across their respective theaters — represents a qualitatively different strategic environment than Western planners faced as recently as 2021.

The Economist report will prompt close attention from defense ministries in Washington, Tokyo, Seoul, and Canberra. If the Russia-China military exchange is confirmed at scale, it would mark one of the most consequential strategic realignments in decades — one that began not with a formal treaty, but with a war that neither side officially started together.
