ANKARA: Turkey said on Monday that an energy exploration vessel that had pulled out of waters claimed by Greece was only undergoing routine maintenance and would return soon.
The Oruc Reis seismic survey ship has been unsettling the strategic eastern Mediterranean region since Turkey sent it along with a small navy flotilla into disputed seas on August 10.
Greece responded by staging navy drills with France and several EU allies near ones Turkey was holding last month.
The escalating row has seen Germany try to mediate a solution and NATO host consultations aimed at avoiding the two alliance members accidentally going to war 鈥� as they almost did over a few contested islands in 1996.
Ankara confirmed on Sunday that the ship had pulled out of the contested waters and returned to the Turkish coast.
Greek Prime Minister Kyriakos Mitsotakis welcomed it as a 鈥減ositive first step.鈥�
But Turkish Foreign Minister Mevlut Cavusoglu said it would be a 鈥渕istake鈥� for Greece to interpret the Oruc Reis鈥檚 withdrawal as a step back by Ankara.
鈥淭his is routine maintenance and (crew) replenishment work,鈥� Cavusoglu said in a televised interview.
鈥淕reece can perceive it as a step back in the face of our determination,鈥� he said. 鈥淚t is suffering the insecurities of a small country.鈥�
The Turkish energy ministry said in a separate statement that after undergoing 鈥渆xamination and care, the vessel will continue its seismic search and research activities.鈥�
Ankara is frustrated that Greece is using its far-flung eastern islands to claim control over waters near the Turkish shore.
The European Union has fully backed Athens and dangled the threat of economic sanctions against Turkey being adopted at a summit planned for September 24-25.
US Secretary of State Mike Pompeo said in Cyprus on Sunday that Washington was also 鈥渄eeply concerned鈥� by Turkish exploration 鈥渋n areas over which Greece and Cyprus assert jurisdiction.鈥�
Turkey directs much of its fury at the so-called 鈥淪eville map鈥� that Greece uses to justify its claims.
The map was drawn up by Spain鈥檚 University of Seville on commission from the European Union in the early 2000s.
It suggests granting full economic zones to Greece鈥檚 small islands in the Aegean and eastern Mediterranean Seas.
Turkey says the map breaches its sovereignty and contradicts past examples of countries鈥� distant islands not being given full economic zones.
Cavusoglu on Monday called the map 鈥渢he cause of all the tension.鈥�
The two sides could enter direct negotiations 鈥渋f (Greece) gives up its maximalist demands. It could forgo the Seville map,鈥� Cavusoglu said.
鈥淏ut there is no good will in Greece. We haven鈥檛 seen it yet.鈥�
