U.S. imposes sanctions on companies over support for sale of Iranian petrochemicals

The United States on Wednesday imposed sanctions on companies based in China and the United Arab Emirates, accusing them of supporting the sale of Iranian petrochemicals as Washington increases pressure on Tehran even as President Donald Trump's term nears a close.

The U.S. Treasury Department in a statement said it blacklisted the four entities for facilitating the export of Iranian petrochemical products by Triliance Petrochemical Co. Ltd., which was hit with sanctions by Washington earlier this year.
