Greece and Egypt agreed to grow their cooperation in fields including energy and security, Greek newspaper Katherimerini reported.
The accord came during a meeting between Greek Prime Minister Kyriakos Mitsotakis and Egyptian President Abdel Fattah Sisi in Cairo on Monday, it said.
The pair exchanged views on regional developments and the need to strengthen trilateral cooperation between Greece, Cyprus and Egypt, Kathimerini cited Sisi as saying.
Mitsotakis pointed to the new environment and energy agreement signed between the two countries, calling it a step that helps both countries’ prosperity.
In August, Egypt and Greece signed an agreement designating an exclusive economic zone in the eastern Mediterranean, in an area containing promising oil and natural gas reserves, which Turkey also lays claim to.
Turkey reacted strongly to the maritime zone agreement, saying it violated the continental shelf of Turkey and Libya, and thereby was “null and void”.
In April, Greece and Egypt signed a programme for bilateral military cooperation following a meeting between officials from the Hellenic National Defence General Staff and their Egyptian counterparts.
The agreement covers a broad range of military activities that will take place in both Greece and Egypt, focusing mainly on joint exercises and training involving all three branches of their armed forces.
Turkey earlier this year began holding its first direct talks with regional rival Egypt, following a decade of strained ties.
Last month, Turkish President Recep Tayyip Erdoğan said it “saddened” him to see Egypt in solidarity with Greece.
