China is planning to deliver air defense systems to Iran within weeks, according to US intelligence. This comes as tensions rise in the region. The Chinese embassy in Washington has denied any involvement in providing weapons to any party involved in the conflict. The intelligence suggests that Beijing is preparing to transfer shoulder-fired anti-air missile systems known as MANPADs, which pose an asymmetric threat to US military aircraft if the ceasefire breaks down. The report also highlights potential use of the ceasefire to replenish certain weapon systems with assistance from key foreign partners. This follows US President Donald Trump's announcement that imports from countries supplying military weapons to Iran will face immediate 50% tariffs.
