Egypt-Greece maritime deal

As a response to the Libya-Turkey maritime deal, Egypt and Greece signed a maritime treaty creating an exclusive economic zone for oil and gas drilling rights in the Mediterranean sea. The deal establishes “partial demarcation of the sea boundaries between the two countries, and that the remaining demarcation would be achieved through consultations.” Egyptian foreign minister Sameh Shoukry and Greek Nikos Dendias signed the deal in Cairo on August 6, it was ratified by the Egyptian president Abdel-Fattah el-Sissi on October 10 and the Greek Parliament on August 27.
On March 2021, after Turkey expressed its will to make an agreement on maritime borders with Egypt, the latter discussed cooperation in eastern Mediterranean with Greece and aimed for further coordination in other areas such as economic, military and security matters.
Turkish response.
Turkish President Recep Tayyip Erdogan called the Egypt-Greece deal “worthless", while the Turkish Ministry of Foreign Affairs made a press release stating: "A maritime boundary between Greece and Egypt does not exist. With respect to Turkey, the so-called maritime delimitation agreement signed today is null and void. This understanding will reflect on the ground and at the table."
Turkey is not a signatory to the UN Convention on the Law of the Sea, which defined the exclusive economic zone of Greece in 1982.
