The Eastern Mediterranean Gateway Act directs U.S. foreign policy to prioritize the Eastern Mediterranean region as a strategic hub connecting the India-Middle East-Europe Economic Corridor (IMEC), a project meant to counter China's growing global infrastructure influence. It focuses on strengthening ties with Egypt, Greece, Cyprus, and Israel through expanded energy cooperation, defense partnerships, and diplomatic engagement, including reviving the "3+1" dialogue format between the U.S., Israel, Greece, and Cyprus. The bill authorizes the Secretary of State to establish formal strategic dialogues with IMEC partner nations, which include the U.S., European Union, Germany, France, Italy, Saudi Arabia, India, and the United Arab Emirates. It also requires several government studies and reports, including an initial implementation report within one year followed by recurring updates over 15 years, an assessment of how IMEC counters Chinese influence, and feasibility studies on creating new bilateral research and development programs modeled on existing U.S.-Israel partnerships. No new funding is appropriated; the bill primarily directs diplomatic prioritization, reporting requirements, and study of potential future programs.
