Lavrov recalled that the Russian side had invited representatives from all United Nations Security Council permanent member nations and from many other countries to attend the Congress of Syrian National Dialogue in Sochi, TASS reported.
"We are thankful to China and Kazakhstan for delegating special envoys to the event," he said.
"However our western partners have confined themselves to sending here (to the Syrian National Dialogue Congress) only junior diplomats from their embassies in Russia. At least we offered, we are ready for dialogue in any formats and at any levels," he stressed.
