The US Treasury Department on Friday announced a new round of sanctions against 10 individuals and companies accused of helping Iran enable its drone and ballistic missile programs.

The sanctions, imposed by the U.S. Treasury Department’s Office of Foreign Assets Control, target “Iran’s military efforts to secure weapons, as well as raw materials used in Iran’s Shaheed series unmanned aerial vehicles and ballistic missile program,” the Treasury Department said in a news release.

The State Department is targeting four more entities with sanctions, the Treasury Department said.

The sanctions also include companies in China, Dubai, Hong Kong and Belarus that the Treasury Department has accused of serving as intermediaries, assisting Iran’s Center for Innovation and Technology Cooperation, CITC, with “financial, material, technical or other assistance.”

According to the finance department, CITC has tried to buy weapons and air defense systems from China.

The Treasury Department said one of the sanctioned companies, Hong Kong-based Mustad Ltd., had helped or attempted to help buy “millions of dollars worth of weapons” from Iran.

“Under President Trump’s decisive leadership, we will continue to take action to keep America safe and to target foreign individuals and companies that provide weapons to Iran’s military for use against U.S. forces,” Treasury Secretary Scott Besant said in a statement.

Secretary of State Marco Rubio said in a separate statement that Friday’s sanctions “hold China-based entities accountable for supporting Iran. The United States will take all necessary action to target third-country entities and individuals that support Iran’s military and defense industrial base.”
