US President Donald Trump issued a stark warning to China on Sunday regarding potential arms shipments to Iran, following a CNN report that indicated China might supply advanced air defense systems. Trump stated, 'If China does that, China is gonna have big problems,' emphasizing the seriousness of the situation. The report claims that China is preparing to deliver shoulder-fired anti-air missile systems, known as MANPADs, which could threaten US military aircraft. Furthermore, there are indications that Beijing may attempt to disguise the origin of these shipments by routing them through third countries. In response, a spokesperson for the Chinese embassy in Washington refuted these claims, asserting that China has never provided weapons to any party involved in the conflict and urged the US to avoid making baseless allegations. This development occurs against a backdrop of fragile relations and ongoing tensions between the US and Iran.
