Heads of European Union Mediterranean states offered full support on Friday for fellow EU member Cyprus in a dispute with Turkey over the ownership of offshore natural gas deposits.
The discovery of lucrative energy reserves has exacerbated tensions between Turkey and Cyprus which date to an ethnic conflict in 1974 that split the island between its Greek and Turkish Cypriot populations. The Turkish-speaking northern part of Cyprus proclaims independence, recognised only by Turkey.
Cyprus said this week it had issued arrest warrants for the crew of a Turkish drill ship it accused of infringing territory over which it claims the right to explore for oil and gas.
Turkey has overlapping claims of jurisdiction for offshore research in the Mediterranean and argues that Turkish Cypriots also have a right to a share of the newfound resources. Ankara said reports of the arrest warrants "crossed the line".
EU leaders in Malta threw their weight behind Cyprus.
"Turkey must stop its illegal activities in the exclusive economic zone of Cyprus," said French President Emmanuel Macron. "The European Union will not show any weakness on this subject."
Greek Prime Minister Alexis Tsipras said: "It's important to signal that the EU should take specific measures if Turkey does not stop its infringing behaviour. Whoever doesn't respect international law must suffer the consequences."
Turkey has bid for EU membership, but its candidacy is frozen, with the EU executive in May saying its hopes of joining were fading because of backsliding on rights and rule of law.
The gathering inMalta came a week ahead of a full summit of EU leaders, which falls at a timewhen a number of top jobs in Europe are up for grabs — including new heads ofboth the European Commission and the European Central Bank (ECB).
Italian PrimeMinister Giuseppe Conte said he hoped the southern EU leaders could worktogether to make sure their interests were respected.
"I hope to get everyone's agreement for greater cohesion on the part of the southern EU states. Sometimes we make the mistake of splitting, while other groups, like those in the north, are more united," he said.
Earlier this week agovernment source in Rome said Italy was ready to back a French candidate tolead the ECB as part of a plan to ensure an Italian retained a seat on thecentral bank executive board.
Conte, who leads agovernment that includes the anti-immigrant far-right League, also expresseddisappointment that the EU had yet to agree a comprehensive immigration policy,with promises unfulfilled to disperse migrants across the bloc.
"It isunacceptable that we continue to declare abstract solidarity for all, but thenfail to translate this into concrete measures," he said.
