Greece wants to be included in UN-sponsored talks in January on the Libya conflict, Prime Minister Kyriakos Mitsotakis said on Sunday, as tensions escalate with neighbours Turkey over the issue.Libya has become another diplomatic front for Greece and Turkey as the traditional rivals jostle over Mediterranean maritime rights and the competing camps in the North African country's conflict."We do not want a source of instability in our neighbourhood. Therefore we want a say in developments in Libya," Mitsotakis told To Vima weekly in an interview."We want to be part of the solution in Libya, as it concerns us too," he said.The UN has said an international conference will be held next month in Berlin to pave the way for a political solution to Libya's ongoing conflict.Libya has been beset by chaos since a NATO-backed uprising toppled and killed dictator Moamer Kadhafi in 2011, with rival administrations in the east and the west vying for power."I have requested, and will do so again with greater insistence, that we participate in the Berlin process," Mitsotakis said.In November, Ankara signed a contentious maritime and military deal with the embattled UN-recognised government in Tripoli.Greece immediately rejected it as baseless, arguing that Turkey and Libya share no maritime border."(Libya) is our natural maritime neighbour, not Turkey's," Mitsotakis said on Sunday.The Turkish deal lays claim to much of the Mediterranean for energy exploration, conflicting with rival claims by Greece and Cyprus.At the same time, Turkey is stepping up military aid to Tripoli, which is battling the forces of military strongman Khalifa Haftar for control of the capital.Mitsotakis on Sunday also addressed recent statements by Turkish President Recep Tayyip Erdogan that called into question sovereignty treaties with Greece.Turkey maintains that several islands and islets near its coasts that are claimed by Greece under longstanding postwar treaties are actually 'grey zones'. "No one should try to blockade us, to trap us in our own coasts or trample on our economic rights," Erdogan said last week.Mitsotakis on Sunday said: "If we cannot work things out, then we should agree to settle the one case that is acknowledged by Greece at an international judicial body, such as the International Court (of Justice) at the Hague.""I am referring to the continental shelf and maritime zones in the Aegean and the eastern Mediterranean," he added.
