Turkey must keep diplomatic balance to find peace between Russia and Ukraine: Erdoğan aide

Turkey must maintain a delicate diplomatic balance following Russia's invasion of Ukraine so that it remains able to help facilitate an eventual negotiated end to the war, Turkey's presidential spokesman said in an interview.

Ibrahim Kalın, who is also Erdoğan's chief foreign policy adviser, said that while Ankara has criticised Moscow's Feb. 24 invasion and actions on the battlefield it would do no good to take a more punitive stance against Russia.

NATO member Turkey, a Black Sea neighbour of the warring nations, has good ties with both and has opposed Western sanctions on Moscow. It has seen tens of thousands of Russians - and some oligarchs' sanctioned yachts - arrive since war began.

Yet it has also supplied Kyiv with armed drones and blocked some Russian naval passage to the Black Sea, and stands alone as having hosted talks between the Russian and Ukrainian foreign ministers and separately between their teams.

"We have opposed this war from the beginning" but also maintained contact with Moscow, Kalin said at the weekend.

"They need someone -- a trusted partner, negotiator, facilitator, moderator -- someone in some position to be able to speak to the Russian side as well as to the Ukrainian side," he told Reuters.

"We have been able to maintain this position since the beginning of the war and I think it is really in everybody's shared interest that everybody maintains a balanced position."

Russian forces began withdrawing from near Kyiv after peace negotiations in Istanbul in late March.

Turkey has hosted no further talks but in recent weeks it proposed carrying out a sea evacuation of wounded fighters holed up in the southern Ukrainian city of Mariupol.

It was unclear when or whether Turkey would host talks for Russian and Ukrainian leaders Vladimir Putin and Volodymyr Zelensky. "There is no magic formula to resolve this overnight," Kalin said.

Asked what might prompt Turkey to take a more pro-Ukraine, punitive stance against Russia, he said: "What good would it do?" It would not "change the outcome nor course of the war at this point," he said.

Yet Kalın pointed to a supportive letter the Biden administration sent to the U.S. Congress on the potential sale of 40 F-16 fighter jets to Turkey as a signal of progress.

"The Biden administration has taken a number of concrete, positive steps to move this thing forward" and receive congressional approval for the deal, which would boost bilateral ties and also NATO defences in challenging times, he said.

"More cooperation and understanding has been underway."
