The United States has sanctioned Turkey over the purchase of of S-400 missiles from Russia. “The United States made clear to Turkey at the highest levels and on numerous occasions that its purchase of the S-400 system would endanger the security of US military technology and personnel and provide substantial funds to Russia’s defence sector, as well as Russian access to the Turkish armed forces and defence industry,” Secretary of State Mike Pompeo said.
“Turkey nevertheless decided to move ahead with the procurement and testing of the S-400, despite the availability of alternative, NATO-interoperable systems to meet its defence requirements,” he said in a statement.
“I urge Turkey to resolve the S-400 problem immediately in coordination with the United States,” he said. “Turkey is a valued ally and an important regional security partner for the United States, and we seek to continue our decades-long history of productive defence-sector cooperation by removing the obstacle of Turkey’s S-400 possession as soon as possible.”
