Ankara, July 26: Turkey's President Recep Tayyip Erdogan said Friday that it planned to start using the Russian S-400 missile defence system -- a bone of contention with the United States -- in April 2020. "In the coming spring, God willing in April 2020, we will be able to start using this system," he told a gathering of his Justice and Development Party (AKP) in Ankara. Washington has reacted to Turkey's purchase of the S-400, which was delivered this month, by kicking the country off its F-35 fighter jet programme.

The US says Russia will be able to glean sensitive technical knowledge about the new fighter if it is operated alongside the S-400. "You won't give the F-35? Very well, excuse me, but we will take measures in this regard and will turn towards others," Erdogan said. He threatened that rising tensions in the relationship could also put at risk a multi-billion-dollar order for Boeing airliners. Emine Erdogan, Turkey’s First Lady Flaunts USD 50,000 Handbag on Trip to Japan and Instantly Gets Hate and Backlash.

Erdogan said he raised the issue with US President Donald Trump during their meeting at the G20 summit in Japan last month. "I told Trump in Osaka... Even if we are not buying the Patriots, we are buying Boeings... We are good clients. But if things continue like this, whether we want to or not, we may have to reconsider." Turkey and the US have also held talks this week on establishing a buffer zone in northern Syria to prevent clashes between Turkish and Kurdish forces.

Ankara sees the Syrian Kurdish YPG militia as a "terrorist" off-shoot of Kurdish insurgents in Turkey, but the YPG has been a key ally for the US in its fight against the Islamic State extremist group. "However the talks with America on setting up a safe zone on Syria's border end, we are determined to destroy the terror corridor east of the Euphrates," Erdogan said.
