“Of course, we did not forget Trump's letter, which has nothing to do with politeness. But our mutual respect does not allow us to keep this issue on the agenda, ”RIA Novosti quoted Erdogan as saying.

According to him, the parties "do not consider this a priority," but, "when the time comes, what is needed will be done."

Earlier media reported that Trump sent Erdogan a letter urging “not to fool around” and “not to let the whole world down” with the military operation “Source of Peace” in Syria.

The Kremlin called the tone of the message very unusual, noting that "such a language is rarely seen in the correspondence of state leaders."
