Paris, France – French President Emmanuel Macron said on Tuesday he was ready for dialogue with Turkey, but it needed to respect the European union’s sovereignty, international law and clarify its actions in places like Libya and Syria.

“We Europeans are ready for dialogue, for the essential construction of a Pax Mediterranea, but not at the cost of intimidation, not at the cost of survival of the fittest, with respect for international law, cooperation and respect among allies,” Macron said in a speech for the United Nations General Assembly.

“These principles are non-negotiable.”

Erdogan discusses Eastern Mediterranean with France’s Macron

Turkish President Tayyip Erdogan and France’s Emmanuel Macron said on Tuesday they had held their first conversation in months following a standoff between the two NATO allies over mounting tensions in the Eastern Mediterranean.

In a statement after a call between the two leaders, the Turkish presidency said Erdogan emphasized the need for using diplomatic opportunities to de-escalate the situation and achieve sustainable negotiations.

The French foreign ministry said following the call, which lasted over an hour, that it hoped a dialogue between Turkey and Greece could continue, and said Macron had called for a similar approach with the GCA.

“He [Macron] urged Turkey to fully respect the sovereignty of European Union member states as well as international law, and to refrain from any further unilateral action which could provoke tensions,” the French foreign office said, adding that Macron and Erdogan had agreed to keep in contact.

Relations between the EU and Turkey are badly strained on a number of issues, including exploration for hydrocarbons in the Eastern Mediterranean, where Ankara has been at loggerheads with EU member states the GCA and Greece.
