Greece and Libya have agreed to resume talks on defining their maritime boundaries for the first time since 2010, Greek officials have said.
The move comes as Athens monitors rival Turkey's deepening diplomatic engagement in eastern Libya.
Technical committees from both countries are expected to meet by October. Greece's negotiating team will be led by Deputy Foreign Minister Alexandra Papadopoulou.
Officials in Athens said the swift positive response from Libya signaled a genuine willingness to restart the negotiations.
The diplomatic push coincides with Turkey’s recent efforts to mend ties with eastern Libyan strongman Khalifa Haftar.
A recent visit to Benghazi by Turkey’s intelligence chief, Ibrahim Kalin, is seen by diplomats as part of an effort to persuade Libya's eastern-based government to ratify a controversial 2019 Turkish-Libyan maritime accord, which Greece deems illegal.
Greek officials said their strategy is independent of Ankara's and involves keeping open channels with both of Libya's rival administrations.
Delegations from both Tripoli and Benghazi, including a son of Mr. Haftar, are expected to visit Athens in the coming weeks.
In a separate initiative, Deputy Foreign Minister Haris Theoharis is scheduled to lead a Greek business delegation to Libya this fall.
