U.S. Secretary of State Mike Pompeo said on July 15 that companies involved in construction of the TurkStream pipeline will be subject to the U.S. penalties unless they stop their works. “It’s a clear warning to companies. Aiding and abetting Russia’s malign influence projects will not be tolerated. Get out now or risk the consequences,” he said.
The U.S. has imposed new sanctions on Turkish company Eren Carbon Graphite Industrial Trading Co Ltd. because of its support for Iran's missile program. "These measures underscore 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."
