China’s Foreign Ministry spokesperson, Guo Jiakun, said Tuesday that claims that China was supplying Iran with weapons were “completely made up.”

China’s rejection of the reports that it may be sending military aid to Iran follows media reports that show otherwise.

For example, satellite imagery shows ships leaving Chinese ports and heading to Iran loaded with sodium perchlorate, which is crucial for the production of ballistic missile fuel.

China pushed back forcefully on the claims.

“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,” its embassy said.

Jiakun added, “We oppose groundless smears or malicious association.”

Meanwhile, Trump warned China in his usual blunt manner that there would be consequences if it were caught red-handed.

“If China does that, China is gonna have big problems, OK?” he told reporters when asked for his reaction to reports that China was preparing to send air defense systems to Iran.
