US officials are intensifying diplomatic efforts with China ahead of the upcoming meeting between President Trump and Chinese leader Xi Jinping, focusing on Iran sanctions. Treasury Secretary Scott Bessent highlighted that China is actively involved in Washington’s campaign against Iranian financial institutions, as restrictions on Iranian airlines are set to take effect on September 23. The US is pushing for broader international cooperation to limit Iran’s access to global financial systems, citing concerns over its nuclear program and regional influence.

Meanwhile, Iran has vowed to retaliate if the US and Israel launch a new attack, with military commander General Hatami warning of a full defense. This comes as Asian financial markets show signs of optimism, with Chinese and Hong Kong stocks rising on hopes that the US and China may extend their trade truce. Investors are closely watching the outcome of the high-stakes talks, which could reshape economic and strategic relations between the two global powers.
