Greece and Saudi Arabia have agreed to set up a bilateral cooperation council.
It comes as part of talks between Greek Prime Minister Kyriakos Mistotakis and Saudi Crown Prince Mohammed bin Salman in Riyadh on Tuesday.
They met ahead of Mitsotakis’ address at the country’s Future Investment Initiative (FII) – a high-profile showcase summit for investors.
Mitsotakis used his address to call on Turkey to stop “aggressive posturing” and agree to maritime negotiations.
“I think we’ve set up our alliances, we’ve drawn our lines very, very clearly,” Mitsotakis said.
“And I do hope that at some point, Turkey will constructively engage with us to resolve the one main outstanding issue we have which is the delineation of maritime shores.”
“We’re always open for dialogue, but we will not be intimidated and we will not accept our sovereign rights to be compromised.”
“I think at the end of the day, Turkey will also realise that this aggressive posturing in the eastern Mediterranean is not going to lead anywhere.”
Tensions between Greece and Turkey have flared recently over energy exploration rights in the eastern Mediterranean.
The two neighbours are at loggerheads over territorial rights in the Aegean Sea, maritime and aviation boundaries, and minority rights.
