The Eastern Mediterranean is no longer just a peripheral zone of Middle Eastern diplomacy; it has become a strategic epicenter of global energy, security, and geopolitical rivalry. In this rapidly evolving theater, the partnership between Cyprus and Israel has emerged as one of the most critical and complex bilateral relationships. Driven by shared energy ambitions, maritime security interests, and balancing against Turkish assertiveness, the two states have built a robust alliance. Yet beneath the surface, this alliance is being tested by maritime boundary disputes, diverging foreign policy alignments, and the lingering uncertainty of regional diplomacy.
The Cyprus–Israel relationship oscillates between deep strategic cooperation and geopolitical friction. While both nations benefit from collaboration on natural gas development and trilateral security cooperation with Greece, recent developments such as Israel’s rapprochement with Turkiye, unresolved Exclusive Economic Zone (EEZ) disputes, and diverging stances on regional conflicts have exposed latent vulnerabilities in their alignment. This article dissects the relationship with granular detail, focusing on the interplay of energy, security, diplomacy, and regional pressure.
Historical Underpinnings: From Distance to Alliance
Cyprus and Israel had historically distant relations for much of the 20th century. Cyprus, despite being geographically close, generally aligned itself with the Arab bloc on issues such as Palestinian statehood and maintained a non-aligned foreign policy during the Cold War. This reflected both ideological concerns and practical diplomatic strategy, as Cyprus sought to maintain balanced ties with the Arab world, crucial for economic and political support. Meanwhile, Israel was closely aligned with Turkiye, particularly after the 1950s, which limited its incentive to engage with Cyprus, a country embroiled in the Cyprus problem, a complex geopolitical conflict that resulted in the division of the island after Turkiye’s military intervention in 1974.
The turning point came after the 2010 Mavi Marmara incident, where Israeli naval forces raided a Turkish aid flotilla headed for Gaza, resulting in ten civilian deaths and a breakdown in Turkish-Israeli relations. This pushed Israel to seek new strategic allies in the region, namely Cyprus and Greece, who shared concerns over Turkish maritime assertiveness.
Thus began a rapid normalization and expansion of ties, evolving into strategic cooperation encompassing energy, defense, intelligence sharing, and regional diplomacy.
Energy Diplomacy and EEZ Disputes
The discovery of major natural gas reserves in the Eastern Mediterranean was a key catalyst in strengthening Cyprus–Israel ties. Israel discovered the Tamar (2009) and Leviathan (2010) gas fields, while Cyprus found the Aphrodite field (2011) in Block 12 of its declared Exclusive Economic Zone (EEZ).
To coordinate exploration and exploitation, Israel and Cyprus signed an EEZ delimitation agreement in 2010, consistent with the UN Convention on the Law of the Sea (UNCLOS). However, Turkiye does not recognize UNCLOS or the Republic of Cyprus and has aggressively challenged the legitimacy of these EEZs.
A critical issue is the Aphrodite Yishai gas reservoir, which crosses the maritime boundary between Cyprus and Israel. Israel has argued that a portion of the field lies within its EEZ and that Israeli companies should be entitled to a share of revenues. The disagreement has stalled the development of Aphrodite, with negotiations ongoing since 2011.
Despite multiple rounds of talks, no unitization agreement has been finalized. This remains a lingering technical commercial dispute that has geopolitical overtones, as any mismanagement could sour the broader alliance.
The EastMed Gas Project: Promise and Politics
In 2016, Cyprus, Israel, and Greece proposed the EastMed Gas Pipeline, a €6 billion project to transport gas from the Levant Basin to Europe via Cyprus and Greece. The pipeline is designed to carry 10–12 billion cubic meters of gas annually to reduce EU dependence on Russian energy. While symbolically significant, the project has faced technical, financial, and political hurdles:
- The depth and complexity of the seabed route make construction expensive and logistically challenging.
- Turkiye has objected vehemently, claiming the pipeline infringes on its claimed continental shelf, particularly after its 2019 maritime delimitation deal with Libya.
- The U.S. withdrew support in 2022, calling the project “financially unviable” and pushing for electrification alternatives like the EuroAsia Interconnector.
Israel’s enthusiasm for EastMed has cooled recently. Talks with Turkiye about exporting gas via existing pipelines to Europe have raised fears in Cyprus that Israel could pivot away from the Greek Cypriot route in favor of economic expedience and Turkish normalization. This adds a strategic ambiguity to the Israel–Cyprus relationship.
Trilateral Security Cooperation with Greece
The trilateral partnership between Israel, Cyprus, and Greece has become one of the most active diplomatic formats in the region. Since its first summit in 2016, it has expanded to include annual high-level meetings, joint military drills, and infrastructure projects:
Key defense collaborations include:
- “Noble Dina” Naval Exercises: Annual drills involving anti-submarine warfare, search and rescue, and maritime interdiction scenarios.
- “INIOCHOS” Air Exercises: Coordinated by Greece, these involve multi-domain training and are often used for testing Israel’s F-35s and Cyprus’s air defense capacity.
- EuroAsia Interconnector: A 1,208 km undersea cable project aiming to link the three countries’ power grids, expected to be operational by 2028.
These initiatives are motivated by a shared perception of Turkish assertiveness as destabilizing. However, analyst Z. Tziarras likes to note that this is a “quasi alliance,” strategically useful but lacking treaty obligations or military guarantees, meaning cooperation remains conditional on current leadership preferences and external shocks.
Israeli-Turkish Rapprochement and Cypriot Unease
In recent years, Israel has worked to repair ties with Turkiye, culminating in the exchange of ambassadors in 2022 and increased energy dialogue. While these moves are welcomed by many international actors, they trigger anxiety in Nicosia. Turkiye has offered Israel the possibility of using its existing pipeline infrastructure to export gas to Europe cheaper and faster than the EastMed pipeline. For Cyprus, this poses a dual threat:
- Economic: It undermines the commercial value of Cyprus’s own energy strategy.
- Political: It risks marginalizing Cyprus in regional energy diplomacy.
Recent meetings between Israeli and Turkish energy ministers have signaled growing momentum for cooperation, though no formal agreement has been signed as of mid 2025. Still, Cyprus views these developments with strategic caution, concerned that its once exclusive partnership with Israel may become a regional triangle where Ankara reasserts influence.
Divergence on Palestine and the UN
Despite being a strategic partner to Israel, Cyprus maintains diplomatic symmetry with Arab states and has long supported Palestinian statehood. It was one of the first European states to recognize the State of Palestine in 1988 and often votes in favor of UN resolutions critical of Israeli actions, particularly those concerning settlement expansion and military operations in Gaza. Cyprus has historically sought to position itself as a bridge between Europe, the Arab world, and Israel. While this position has been largely respected by Israel, it can at times create diplomatic frictions, especially during periods of intense regional violence or sensitive UN resolutions.
Both states, however, have demonstrated an ability to compartmentalize differences, keeping strategic cooperation separate from their ideological divergences on the Palestinian issue.
External Actors and Regional Balancing
The Cyprus–Israel axis does not operate in isolation. It intersects with a wider constellation of regional powers and international institutions:
- European Union: Strongly supports Cyprus’s EEZ rights and opposes Turkish drilling. The EU has backed infrastructure like the EuroAsia Interconnector.
- United States: A close Israeli ally, the U.S. lifted its arms embargo on Cyprus in 2020, signaling support for its regional role. However, its withdrawal from East Med support indicates a preference for de-escalation over entrenchment.
- Egypt: A key player in the EMGF, it shares energy goals with Cyprus and Israel and maintains its own large gas infrastructure.
- Russia: Historically supported Cyprus diplomatically, but its regional role has been weakened by the war in Ukraine.
- Lebanon: Shares a maritime boundary dispute with Israel. Recent U.S.-brokered agreements on maritime boundaries have opened the door to future EMGF expansion, potentially including Lebanon in broader frameworks.
This growing web of energy diplomacy and overlapping claims underscores the need for structured, rules-based conflict management in the region.
Conclusion
As Cyprus and Israel continue to navigate the choppy waters of Eastern Mediterranean geopolitics, their relationship stands as a test case for modern alliance building in contested regions. The strategic rationale remains solid: shared energy corridors, joint security interests, and a common stance against unilateral regional dominance, particularly by Turkiye. However, as the geopolitical chessboard shifts, the durability of this alliance depends on adaptability, trust, and mutual clarity of intent.
For Cyprus, the challenge lies in ensuring that its sovereignty and maritime claims are not sidelined in Israel’s broader regional recalibrations, especially if ties with Ankara deepen. For Israel, maintaining credibility as a dependable partner while pursuing diversified energy and diplomatic options will require a delicate balance of pragmatism and principle.
Ultimately, Cyprus–Israel tensions are not a sign of a failing alliance but of one grappling with the realities of multipolar diplomacy. If managed wisely, this relationship can serve as a cornerstone for regional energy stability, maritime order, and strategic cooperation in one of the world’s most volatile maritime zones.
