China on Monday rejected "groundless" reports alleging that Beijing is planning to send weapons to Iran.

"China always acts prudently and responsibly on the export of military products, and exercises strict control in accordance with China’s laws and regulations on export control and due international obligations," said Chinese Foreign Ministry spokesperson Guo Jiakun during a regular news conference in Beijing, The Caspian Post reports, citing Anadolu Agency.

Guo expressed Beijing's opposition to this "groundless smear and ill-intentioned association."

CNN reported on Saturday, citing sources familiar with recent assessments, that US intelligence suggested China may supply Iran with new air defense systems in the coming weeks.

The report said Tehran could be using the ceasefire period to restock certain weapons systems through third countries, with support from key international partners.

The systems in question were reported to be shoulder-launched anti-aircraft missiles, known as MANPADS.
