Cyprus and Lebanon have sealed a long-delayed maritime boundary deal that both governments see as a strategic breakthrough for the eastern Mediterranean, signing the agreement in Beirut on Wednesday to lock in a shared offshore line and open the way for deeper energy cooperation. The accord, based on the median line between the two countries, defines their exclusive economic zones after nearly two decades of talks and political delays.
Cypriot President Nikos Christodoulides traveled to Beirut for the signing ceremony with Lebanese President Joseph Aoun, underscoring the importance both sides attach to the deal. Christodoulides said the agreement reflects the strength of ties between the neighbors and sends “a strong political message” that they will continue to deepen cooperation in accordance with international law and the UN Convention on the Law of the Sea.

The two leaders also agreed to study the feasibility of an electricity interconnector between Cyprus and Lebanon, part of a wider discussion on closer collaboration in energy, telecommunications, and tourism.
Talks over the maritime line began in 2007 but stalled as Lebanon wrestled with political paralysis and a separate, high-stakes dispute with Israel over overlapping offshore claims. That standoff eased in 2022, when Lebanon and Israel reached a US-brokered maritime deal that allowed exploration to proceed on both sides of their frontier.
For Cyprus, which already has maritime agreements with Israel and Egypt, the new demarcation with Lebanon helps consolidate its role in regional energy planning. For Beirut, emerging from years of economic crisis and institutional fragility, the deal offers a clearer framework for attracting investment in offshore gas and undersea infrastructure projects.
