President Trump has warned that China could face significant consequences if they deliver air defense systems to Tehran, while the US is engaged in a war with Iran. US intelligence sources have suggested that China is planning to send shoulder-fired anti-air missile systems known as MANPADs to Tehran through third parties in an attempt to conceal the weapons transfer. China has denied these reports, calling them "entirely fabricated" and stating it always abides by international law and its international obligations. The Iranian Foreign Minister, Abbas Araghchi, has claimed that China and Russia are engaged in "close cooperation" during the Iran war.
