US President Donald Trump has made clear his opposition to Turkey's purchase of the Russian S-400 missile defense system, a move that has raised eyebrows among Turkey's NATO allies and provoked anger in Washington.
Speaking to Turkish President Recep Tayyip Erdogan at the G20 summit in Osaka, Japan, on June 29, 2019, Trump said that the purchase was 'a problem' and that it was 'not good' for the two countries' relationship.
Washington has given Turkey until July 31 to give up the deal, which it considers incompatible with Ankara's participation in the F-35 fighter jet programme. If Turkey does not comply, it will be blocked from purchasing F-35 fighter jets and Turkish pilots currently training in the US will be expelled.
Turkey has remained committed to the purchase, with Erdogan saying earlier this month that the deal was 'of prime importance' to his country.
Trump and Erdogan met on the sidelines of the G20 summit, where they discussed the S-400 issue and the impact it could have on their strategic partnership.
