United States Secretary of State Marco Rubio is set to visit Athens on October 3 to participate in the 6th Greece-US Strategic Dialogue, with discussions focusing on defense, energy and regional developments.
The diplomatic visit comes during an intense phase of contacts between Athens and Washington. Greek officials noted that while October 3 is the targeted date, the schedule remains subject to potential adjustments driven by broader regional events.
Rubio is scheduled to hold talks with Greek Foreign Minister Giorgos Gerapetritis, while a meeting with Greek Prime Minister Kyriakos Mitsotakis is considered highly likely.
Bilateral Meetings and Delegation Plans
Under plans currently being formed, the schedule may also include bilateral meetings with Greek Minister of National Defense Nikos Dendias, Minister of Maritime Affairs and Insular Policy Vasilis Kikilias, and Minister of Environment and Energy Stavros Papastavrou.
The full composition of the accompanying American delegation has not been finalized. United States Secretary of Defense Pete Hegseth has been named as a potential attendee, though his presence has not been locked in.
The bilateral meeting between Rubio and Gerapetritis follows earlier communications between the two foreign ministers in January, when they discussed preparations for the Athens summit and broader security issues in the Eastern Mediterranean and the Middle East.
The upcoming summit represents a major fixture in bilateral diplomatic relations, providing a formal structure for senior American and Greek cabinet officials to align foreign policy and defense strategy.
Defense Agreement Renewal
A central priority on the agenda is the renewal of the Mutual Defense Cooperation Agreement, the foundational defense treaty governing military cooperation between the United States and Greece.
First signed in 1990 and updated periodically through supplementary protocols, the agreement allows United States forces to operate from key Greek military installations, including Naval Support Activity Souda Bay in Crete and military facilities in Alexandroupoli and Larissa.
In recent years, updates to the defense accord have expanded joint training exercises, infrastructure modernizations and defense integration, solidifying Greece as a critical anchor for NATO operations in Southeastern Europe.
Energy Security and Regional Hubs
United States Ambassador to Greece Kimberly Guilfoyle publicly prepared the ground for the upcoming visit during an address at the 10th Southeast Europe Energy Forum in Thessaloniki.
Speaking at the forum, Guilfoyle announced that Rubio would arrive in Greece within weeks. She directly linked the visit to Washington's strategic emphasis on Greece, describing the nation as an important ally and a critical energy partner.
Guilfoyle highlighted Greece's essential role in the Vertical Corridor initiative, a specialized energy network designed to transport natural gas northbound through Southeastern Europe, supporting regional efforts to eliminate reliance on Russian energy supplies.
In subsequent remarks, Guilfoyle noted that Rubio's visit would not be a mere formality, but was structured to yield substantive and productive discussions reflecting the high level of relations reached between Athens and Washington.
Energy negotiations are expected to place heavy emphasis on Greece's growing position as a principal transit hub for American liquefied natural gas bound for Central and Eastern Europe.
Through operational import terminals such as the Revithoussa LNG facility and new floating storage regasification units off Alexandroupoli, Greece has emerged as a key entry point for American natural gas shipments replacing traditional pipeline routes.
The combination of upgraded defense agreements, energy transit expansion and regional security talks reflects the deepening alignment between the United States and Greece across multiple strategic domains.
