The U.S. has imposed new sanctions on a Turkish company because of its support for Iran's missile program.
Eren Carbon Graphite Industrial Trading Co Ltd. is accused of violating the 2000 Iran, North Korea and Syria Nonproliferation Act (INKSA).
Twelve other entities and individuals in China, Iraq and Russia were also sanctioned on the same grounds.
The State Department named the Chinese as Luo Dingwen and the three Chinese entities as Baoding Shimaotong Enterprises Services Co. Ltd, Gaobeidian Kaituo Precise Instrument Co Ltd, and Wuhan Sanjiang Import and Export Co Ltd.
"The imposition of these measures underscores that Iran’s missile program remains a significant proliferation concern," the State Department said Feb. 25, adding that it is "consistent with our efforts to use all available measures to prevent Iran from advancing its missile capabilities."
U.S. Secretary of State Mike Pompeo said the sanctions were issued under the Iran, North Korea and Syria Nonproliferation Act that affords the United States the ability to impose sanctions against those who aid the three countries in the proliferation of weapons.
The two-year discretionary sanctions, he said, were determined following a periodic review of "sanctionable activity" and will restrict the 13 individuals and entities from U.S. government procurement, assistance and exports.
"We will continue to use all available measures to prevent Iran from advancing its missile capabilities," Pompeo said on Twitter.
