Overview

  • Presidents Joseph Aoun and Nikos Christodoulides signed the agreement at the Baabda presidential palace in Lebanon.
  • The accord follows Lebanon’s 2022 U.S.-mediated maritime deal with Israel and cabinet ratification last month.
  • The pact removes key legal barriers to joint offshore work and energy cooperation, with seismic surveys and licensing rounds still required.
  • Lebanon has yet to register any commercially viable offshore discoveries despite hopes that new exploration could aid its battered economy.
  • Syria remains the only neighbor without a delineated maritime boundary with Lebanon, while Cyprus projects some gas could reach Europe as early as 2027.
