President Tayyip Erdogan said he will discuss buying U.S. Patriot missiles with President Donald Trump this month, saying his personal bond with the U.S. leader could overcome a crisis caused by Ankara buying Russian air defence systems.
Turkey's purchase of the Russian S-400 missile system in July raised the prospect of U.S. sanctions, and the State Department has said an offer to sell Raytheon Co's Patriot missile defence system to Ankara has expired.
However Erdogan told Reuters he had discussed buying Patriots in a phone call with Trump two weeks ago and would follow up when they meet at the U.N. General Assembly, which opens next week.
"I said no matter what package of ... S-400s we get, we can buy from you a certain amount of Patriots," Erdogan told Reuters on Friday.
"But I said we have to see conditions that at least match up to the S-400s," Erdogan said, adding that he was referring to the possibility of joint production and favourable lending terms.
"He (Trump) said: 'Are you serious?' I said: 'Yes'," Erdogan said, adding that he told Trump they would discuss it in greater detail when they meet.
Asked whether he would also ask Trump to prevent the U.S. Treasury imposing a heavy fine on Turkey's mainly state-owned Halkbank for violating U.S. sanctions on Iran, Erdogan said he was confident they could avoid such a "mistake", citing what he said was "a different kind of trust" between the two men.
"In my opinion a country like the USA will not want to hurt its ally Turkey any more. This is not a rational behaviour," he said in an interview at the Ottoman Dolmabahce palace complex on the Bosphorus in Istanbul.
Erdogan and Trump will also discuss plans to establish what Turkey describes as a safe zone along 450 km (280 miles) of Syrian border stretching from the Euphrates river to the Iraq border, a region controlled mainly by U.S.-backed Syrian Kurdish YPG fighters.
On Sunday the two countries launched joint military patrols in the area, but Erdogan says that Washington has dragged its feet in an operation Turkey sees as crucial to driving the YPG, which it designates a terrorist group, away from its border.
Turkey has warned it will act alone if the safe zone is not established this month, raising the prospect of a third Turkish military incursion into northern Syria in three years.
"The peace corridor is the essential thing. We will not allow a terror corridor on our borders and we will take whatever steps are necessary on this subject," he said.
