US targets China, Iran-based firms in fresh Iran sanctions

April 29 (Reuters) - The United States on Tuesday imposed sanctions on a network based in Iran and China that it accused of procuring ballistic missile propellant ingredients on behalf of Iran's Islamic Revolutionary Guard Corps as President Donald Trump's administration seeks to increase pressure on Tehran.

The U.S. Treasury Department in a statement said it was targeting six entities and six individuals as part of the action, which comes as the Trump administration has relaunched negotiations with Iran over its nuclear program.
