Assistant Secretary of State for European and Eurasian Affairs Wess Mitchell on Tuesday said, the United States threatened to impose sanctions on Turkey, if it buys Russia's S-400 air defense systems.
It would be hard to restore relations between the US and Turkey if this happens, he added.
"We made it clear that is Turkey buys S-400s. there will be consequences. We will introduce sanctions within Countering America's Adversaries Through Sanctions Act (CAATSA)," Sputnik quoted Mitchell as saying.
"We believe that we have the existing legal authorities that would allow us to withhold transfer under certain circumstances, including national security concerns," Mitchell told the US Senate Foreign Relations Committee.
Earlier this month, Turkish Foreign Minister Mevlut Cavusoglu slammed Washington for creating artificial crises is the West's style, referring to the Senate's move to block F-35 supplies over Ankara's intention to buy Russia's S-400 air defense systems.
