A deepening technological alignment between China and Iran is reshaping the military balance in the Middle East, with Beijing's advanced surveillance and navigation systems enhancing Tehran's ability to conduct precision strikes.

The cooperation has enabled Iran to improve the accuracy of its missiles and drones, raising concerns over the growing lethality of its operations against both military and civilian targets.

Hidden support

While large-scale Chinese arms transfers to Iran declined following international sanctions regimes in the 1990s and 2000s, current support has shifted toward less visible channels. Beijing's support now flows "in the form of components that could be used in both civilian technologies as well as missiles and drones," the New York Times reported April 15.

In February 2025, the US Department of the Treasury sanctioned six entities based in China and Hong Kong, accused of procuring materials for Iran's ballistic missile and unmanned aerial vehicle programs, highlighting Washington's concerns about indirect supply chains sustaining Tehran's military advances.

China-Iran military cooperation has deepened since the signing of their 2021 comprehensive cooperation agreement, with analysts noting an acceleration in coordination in the lead-up to US-Israeli military operations against Iran that began on February 28.

Strike chain

Emerging assessments suggest that China's role extends beyond material supply. A March 20 report by the Small Wars Journal indicated that Beijing has "significantly contributed intelligence support, satellite navigation, radar systems, and electronic warfare technologies that augment Iran's targeting capabilities."

Chinese commercial satellite imagery, BeiDou navigation, and other dual-use technologies are helping Iran assemble the surveillance, tracking, and guidance links of a modern kill chain -- one Tehran would struggle to sustain without Chinese Communist Party backing.

The Pentagon said in December that China-based commercial satellite firms had participated in business exchanges with Iran's Islamic Revolutionary Guard Corps (IRGC), reinforcing concerns that ostensibly civilian Chinese space and technology assets are feeding into Iran's targeting ecosystem.

Satellites expose targets

At the center of this evolving capability is the integration of Chinese commercial satellite platforms and navigation infrastructure.

Chinese firm MizarVision has published high-resolution satellite imagery of US and allied military assets in the region, raising concerns among Western defense officials about the operational implications of commercially available intelligence. Such platforms could help Iran target objects "as small as 0.3 square meters," military experts told ABC News on April 6.

"We're seeing targets, including a US E-3 Sentry plane, being hit with incredible precision. Our forces would take this threat very seriously -- and rightfully so," said Major General Gus McLachlan, a retired Australian military general, citing an attack on a US command-and-control aircraft at a Saudi air base in late March.

In February, MizarVision released satellite imagery showing eleven US F-22 fighter jets deployed at Israel's Uvda Air Base, The Times of Israel reported February 26, highlighting the extent to which open-source or commercial intelligence is exposing sensitive military positions.

BeiDou guides missiles

Analysts increasingly point to Iran's potential use of China's BeiDou Navigation Satellite System as a factor behind improved missile guidance.

The system, Beijing's alternative to the Global Positioning System (GPS), provides global positioning, navigation, and timing services and has become a cornerstone of China's technological outreach.

During the ongoing conflict, Iranian missiles are "more accurate compared to the war that took place eight months ago, raising many questions about the guidance systems of these missiles," Alain Juillet, former director of intelligence at France's external intelligence agency, told France's independent Tocsin podcast in March.

Beyond immediate battlefield effects, the conflict is also offering Beijing an opportunity to test and refine its systems under real-world conditions. Researchers say data gathered from Iranian operations could help China evaluate the performance of its technologies against advanced Western military platforms.

The conflict allows China to "assess the effectiveness of its systems against American fifth-generation fighter aircraft like the F-35," Theo Nencini, a research fellow at the ChinaMed Project research platform, told Al-Jazeera in March. He also noted that the conflict has helped China collect valuable data on the US's ability to intercept Iranian missiles and drones guided by BeiDou.

Costs bite back

Analysts said the strategic benefits of the Iran-China partnership may be offset by rising economic costs.

While Beijing sustains ties that help Iran weather war and sanctions, Chinese authorities in early April capped fuel-price increases at 420 yuan a ton for gasoline and 400 yuan for diesel -- well below the 800 yuan and 770 yuan rises that China's pricing mechanism would otherwise have triggered, according to an April 7 report by the Wall Street Journal.

The move underscores the political paradox for Chinese leader Xi Jinping as the costs of supporting Tehran spill back onto consumers at home.

CNN reported on April 11 that US intelligence indicates China is preparing to deliver new MANPADS, or shoulder-fired anti-air missile systems, to Iran within weeks, in a sign Beijing's support may be moving beyond dual-use technology toward more direct efforts to help Tehran replenish its defenses.

The report said there were indications Beijing was seeking to route the shipments through third countries to mask their origin.
