The US State Department said that Secretary Anthony Blinken discussed with his Turkish counterpart Mevlut Cavusoglu ways to enhance coordination and the unity of the North Atlantic Treaty Organization (NATO) regarding the Russian threat against Ukraine.
The State Department added that Blinken affirmed the shared commitment to Ukraine's sovereignty and territorial integrity, noting President Erdogan's involvement in supporting a diplomatic solution.
For its part, the Turkish Foreign Ministry said that Minister Mevlut Cavusoglu briefed his American counterpart on the Turkish initiative to reduce tension between Russia and Ukraine through dialogue.
And the White House said in a statement that US National Security Adviser Jake Sullivan and Ibrahim said, a senior adviser to the Turkish president, spoke last Tuesday and discussed their commitment to "deter further Russian aggression against Ukraine."
And Turkish diplomatic sources said last January that both Russia and Ukraine were open to the idea of Turkey playing a role in easing tension between the two countries.
Western countries, led by the United States, accused Russia of massing its forces near the Ukrainian border, and Washington threatened to impose sanctions on Moscow if it launched an attack on Ukraine.
Russia rejects the accusations about the movements of its forces inside its territory, and denies the existence of any aggressive plans it has towards Ukraine.
