In as televised interview, Recep Tayyip Erdogan praised a recent trilateral summit held in the Russian resort city of Sochi with the leaders of Russia and Iran, saying it was "very productive and useful".
According to Hurriyet daily he said the next such summit on the Syrian conflict would be held in Turkey.
In addition, Erdogan reiterated the need for Washington to make good on its promise to evacuate the YPG from northern Syria's Manbij district west of the Euphrates River, stressing there has not yet been a step in this direction.
"Manbij is actually not the place of these terror organizations," he said.
"We will do whatever it takes for our national security," he asserted, noting Ankara would continue to strive for finding mutual ground as long as Tehran and Moscow maintained their attitude.
Erdogan slammed Washington for arming YPG militants, saying it had sent 23,000 trucks loaded with weapons to them.
Turkey considers the YPG as a terrorist organization due to its links with the PKK, which is listed as a terror group by Ankara, the U.S., and the EU.
In December of last year, U.S. President Donald Trump made a surprise announcement that the U.S. would be withdrawing all of its troops from Syria and said IS had been defeated in the country.
