Turkish President Tayyip Erdogan is touting "outstanding" relations with the US amid tensions over a US decision to arm Kurdish fighters.
Erdogan met at the White House with President Donald Trump on Tuesday, and both called relations between the two NATO allies strong.
Erdogan said his visit would "mark a historical turn of tide" and hailed "outstanding relations" between the nations.
It was an especially positive tone considering the tensions over Washington's decision to arm the Syrian Kurdish YPG militia that Ankara regards as an extension of the outlawed Kurdistan Workers Party (PKK).
"There is no place for the terrorist organisations in the future of our region," said Erdogan, speaking through a translator.
He added that the activities of the YPG and its political arm in the region, the PYD, "will never be accepted".
US officials on May 9 disclosed Trump's approval of plans to supply the YPG as it advances toward the Islamic State stronghold of Raqqa in Syria.
Turkey has been a crucial partner in the US-led coalition against Islamic State forces. The US alliance with Turkey has proven pivotal in the battle against Islamic State in Syria, providing the coalition with access to Turkey's Incirlik air base to wage strikes against the militants.
Erdogan had pledged to use the White House meeting to try to get Trump to change course on the YPG.
Trump and Erdogan both emphasised the positive.
"The relationship that we have together will be unbeatable," Trump said.
The visit was further complicated by Turkey's calls for the US to take steps to extradite Turkish cleric Fethullah Gulen.
Erdogan blames Gulen supporters for a failed coup attempt last July and has conducted a crackdown on them, drawing criticism from Washington.
Gulen has denied involvement in the coup and remains in the US.
