US President Donald Trump has vowed to initiate an "economic war" against Iran, warning nations against providing support to the Islamic Republic. The move comes amidst escalating tensions following attacks attributed to the US and Israel. China is Iran’s largest trading partner, with $32.5 billion in trade in 2024, primarily involving Iranian hydrocarbon exports and Chinese industrial imports. The United Arab Emirates are also a significant partner, supplying 30.6% of Iran’s imports, valued at around $21 billion. Trump has already sanctioned Chinese companies accused of importing Iranian oil and aiding its armament, though China has stated it will disregard these sanctions. These figures do not account for illicit trade or strategies employed to circumvent existing economic sanctions, making a complete assessment challenging.
