US President Donald Trump

Ties between the United States and its NATO ally have been strained by Washington’s support for the YPG Kurdish fighters in the battle against Islamic State in Syria. Turkey considers the YPG a terrorist group.

Ankara has also been frustrated by what it sees as Washington’s reluctance to extradite the Muslim cleric Fethullah Gulen. Turkey blames Gulen, who has lived in Pennsylvania since 1999, for last year’s failed coup.

“Noting the strategic partnership between Turkey and the United States, the two leaders emphasized the importance of continuing to work together to further strengthen bilateral relations and increase stability in the region,” the Turkish Presidency said in a statement.

The two leaders agreed to meet in New York at the United States General Assembly, scheduled for this month.
