Turkish President Recep Tayyip Erdogan's congratulatory letter to his Russian counterpart Vladimir Putin on Russia's national day requires no response, the Kremlin spokesman Dmitry Peskov said.
"This is a protocol and common practice in international relations. Generally, such messages require no response. The message did not include any substantial points, unfortunately," Sputnik cited him as saying.
The spokesman noted that difficult diplomatic relations between countries are not always ground to stop sending congratulatory messages.
