Speaking at the United Nations Sustainable Development Summit, Erdogan recalled that Turkey has been hosting 3.6 million Syrian refugees and has spent $40 billion for them.
He claimed that Ankara has been making efforts to ensure peace in Idlib, which he said hosts 4 million residents and was on the brink of a humanitarian crisis.
Since 2016, Turkey’s Euphrates Shield and Olive Branch operations in northwestern Syria have occupied the region controlled by the Kurdish forces.
"Now we are preparing to clean the east of the Euphrates from terrorist organizations," said Erdogan
"We aim to ensure that both the Syrians in our country and our brothers who reside in the region will contribute to reconstruction of Syria when peace is maintained," said the president.
Erdogan also called on world leaders at the summit to back Turkey's efforts to do so.
Syria has been locked in a vicious civil war since early 2011.
Hundreds of thousands of people have since been killed and more than 10 million others displaced, according to UN figures.
