US threatens sanctions on Iran's trading partners, China's role unclear

The US has threatened severe sanctions against any country or entity maintaining economic ties with Iran, launching a campaign to isolate Tehran economically. The move aims to achieve what military force has not, though its application to China remains unclear. China, Iran's largest trading partner and buyer of an estimated 80% of its shipped oil last year, has signaled resistance to US pressure. Treasury Secretary Scott Bessent warned no one is beyond US sanctions' reach, while Iran vowed retaliation through military or cyber means. The announcement comes nearly six months after a US-Israel attack killed Iran's supreme leader, with hardliners strengthening their grip. The UAE has suspended trade ties with Iran, while Turkey has yet to respond.
