Iran is nearing a deal with China to purchase advanced CM-302 supersonic anti-ship cruise missiles, according to a report citing multiple sources familiar with the negotiations. The development comes as the United States increases its naval presence near Iran amid rising regional tensions and warnings from President Donald Trump of possible military action.

The CM-302 missiles, with a reported range of about 290 kilometres, are designed to fly low and fast to evade ship defences. Weapons experts say the system would significantly enhance Iran’s ability to target naval assets in the region, potentially shifting the strategic balance in the Persian Gulf and surrounding waters.

Negotiations between Tehran and Beijing reportedly began at least two years ago but accelerated after a brief conflict between Israel and Iran in June. Senior Iranian officials, including the deputy defence minister, travelled to China as talks advanced, though details such as the number of missiles and financial terms remain unclear.

If completed, the deal would mark one of the most advanced weapons transfers from China to Iran in recent years, deepening military ties between the two countries. The potential agreement unfolds against a backdrop of renewed sanctions and joint naval exercises involving China, Iran and Russia, further complicating efforts by the United States to restrain Iran’s missile and nuclear ambitions.
