Turkey's President Recep Tayyip Erdogan said on Friday that the Trump administration did not appear to portray a united stance on its withdrawal of the US forces from Syria.
In a televised interview, 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."
He added that the next Sochi summit on Syria would be held in Turkey.
In December, Trump made a surprise announcement that the US would be withdrawing all troops from Syria, and said Daesh had been defeated in the country.
Since then, no troops have been withdrawn, however, last month the Pentagon confirmed additional troops were being sent to protect American forces and equipment as they prepare to leave.
