China Plans to Supply Iran with Shoulder-Fired Missiles, Escalating US-China Tensions

China is reportedly preparing to transfer up to 400 shoulder-fired missiles to Iran, marking a significant shift in Beijing's cautious approach toward Tehran. Until now, China has supported Iran diplomatically and supplied dual-use components but avoided direct sales of advanced weaponry. The deal, valued at $60 to $70 million, involves portable air defense systems QW-12 and FN-16, capable of targeting helicopters, drones, and low-flying aircraft. The first shipment is expected within weeks, potentially traveling from western China through Pakistan to Iran.

This move challenges previous US President Donald Trump's warnings that arms sales to Iran by China or Russia would have severe consequences. Trump claimed Chinese President Xi Jinping had promised not to sell weapons to Iran, a pledge now called into question. Beijing denies the reports, and Pakistan has also denied involvement in the transfer route. Experts suggest China's motivation stems from strategic rivalry with the US and a desire to counter American dominance in the Middle East, rather than deep allegiance to Iran.

China has historically balanced its Iran relations carefully, avoiding jeopardizing ties with Gulf states like Saudi Arabia and the UAE while benefiting from Iranian oil supplies and strategic trade routes linked to the Belt and Road Initiative. Strengthening Iran's air defenses could complicate US and Israeli military operations in the region and keep American focus diverted from other strategic areas such as Taiwan and the Indo-Pacific.

Analysts also propose that China may be testing its weapon systems against US technology in real conflict zones or using the arms deal as leverage in broader negotiations with Washington, especially amid stalled US arms sales to Taiwan. Despite the potential diplomatic costs, Beijing appears willing to take greater risks to bolster Iran's military capabilities while hoping to avoid escalation that would disrupt vital energy shipments through the Strait of Hormuz.

The development signals a notable departure from China's previous restraint and could intensify geopolitical tensions involving the US, Iran, and regional Gulf countries.
