Turkish President Recep Tayyip Erdogan said Ankara intends to buy another set of Russian S-400 air defense systems despite pressure from Washington.
"We were crystal clear when we wrote the CAATSA [Countering America's Adversaries Through Sanctions Act] law: Sanctions are mandated for any entity that does significant business with the Russian military or intelligence sectors," Menendez said on Monday. "Any new purchases by Turkey must mean new sanctions."
Last week, Erdogan said the continuous pressure on Turkey over its purchase of the S-400 system is unacceptable. Erdogan pointed out that the United States made a mistake by refusing to sell Turkey F-35 fighter jets under the pretext of the S-400 purchase.
Erdogan is scheduled to meet with Russian President Vladimir Putin on Wednesday in Sochi to discuss bilateral trade, but also cover pressing issues, including Syria, Afghanistan and Libya.
