Lieutenant Colonel Mike Andrews, a US Defense Department spokesman, said a decision had been made in late 2019 "to honour existing contractual arrangements and accept delivery of parts that were already on contract."
President Trump, who made the remarks during an interview with Fox Business Network’s Maria Bartiromo, said the US makes parts for F-35 jet all over the world and cited challenges of global cooperation.
Turkey and Russia pledge to continue cooperation in the military and energy spheres as well as in Syria.
Foreign Minister Mevlut Cavusoglu warned if the US imposes sanctions, Incirlik Air Base and Kurecik Radar Station, where US soldiers are stationed, in Turkey would come into question.
Foreign Minister Mevlut Cavusoglu said more missile systems are essential for Turkey's security and despite the purchase of Russian S-400s, Ankara is open to buying US-made Patriots.
Turkish Defence Minister Hulusi Akar said Turkey would have to look for alternatives if it could not acquire US F-35 jets over the purchase of the advanced Russian S-400 air-defence system.
The Russian-made defence hardware will be activated after relevant military personnel are trained, says Turkish defence minister.
Ankara is not only an F-35 fighter jet customer but also a partner, Turkish President Erdogan underlined at a Justice and Development Party's parliamentary meeting.
Talks being held at the bilateral level and not under NATO supervision, Turkish presidential spokesman Ibrahim Kalin says.
The Turkish president says that giving up the Russian missile defence system would be an interference in Turkey's sovereignty rights but is open to buying the US's Patriot missile defence system as well.
Even though the kingdom’s possible purchase of missile systems from Moscow has been in the works for a few years, the country has not finalised a deal with Russia’s President Putin.
Ankara and Moscow are also discussing potentially co-manufacturing a few components of the jets, Turkish sources said.
