The US Department of the Treasury has announced a new sanctions package targeting ten individuals and companies in China and Hong Kong over allegations that they supplied materials, equipment and technologies used in the manufacture of Iran’s Shahed unmanned aerial vehicles.

The department said Washington would continue targeting foreign entities involved in supporting Iran’s prohibited activities, including companies operating in the aviation sector and other businesses engaged in illicit trade with Tehran. It also warned international financial institutions against facilitating such transactions, adding that secondary sanctions could be imposed on entities linked to independent Chinese oil refineries.

The newly designated entities include Yoshita Shanghai, Elite Energy, HK Hsin and Mostad, which Washington accuses of providing financial and logistical assistance to Iran’s Islamic Revolutionary Guard Corps (IRGC). The measures also cover Belarus-based Armory Alliance and China’s Hitex Insulation, accused of supplying materials used in ballistic missile manufacturing, as well as Iran’s Pishgam Electronic, which has allegedly supplied engines for unmanned aircraft.

Meanwhile, US Treasury Secretary Scott Bessent said on Saturday that Washington would continue its economic pressure campaign against Iran without easing its efforts. He stressed that foreign entities providing military assistance or supplying weapons to the Iranian armed forces could face sanctions as part of the US administration’s broader efforts to curb Iran’s military capabilities and restrict funding for its activities.
