The U.S. State Department, in a memo to U.S. senators, expressed its disagreement with the sanctions bill against Turkey over Ankara’s military operation in northeast Syria and the purchase of Russian S-400 anti-aircraft missile systems, The Daily Beast news portal reported referring to a document.

This is a bill prepared by Republican James Risch (Idaho) and Democrat Robert Menendez (New Jersey). Previously, it was approved by the foreign affairs committee of the upper house of the American legislature and should now be considered by the Senate of the whole, where it can be amended.

The initiative obliges the Washington administration to impose restrictions on Ankara amid the purchase of the S-400 under the CAATSA (On Countering America's Adversaries Through Sanctions), and also prohibits US authorities from providing defense goods, services, and technology to the Turkish government if they can be used during surgery in Syria.

According to the US Foreign Ministry, the introduction of a number of restrictions set forth in the bill could lead to increased dependence of Turkey on Russia or other opponents.

In the absence of stockpiles of American weapons, these restrictions may push Turkey to seek an alliance with Russia as its main source of weapons, which will have an impact on NATO’s collective defense, the note said. The State Department also believes that legislative initiative could harm trade relations between Turkey and the US in the defense sector and adversely affect the interests of national security of the United States.

In this regard, the State Department calls for amendments to the bill aimed at mitigating some restrictive measures by providing the opportunity to apply exceptions to their implementation.
