Secretary of State Marco Rubio Signs Landmark Nuclear Cooperation Agreement with Hungary
BUDAPEST, Hungary — In a significant step to bolster transatlantic relations and energy collaboration, U.S. Secretary of State Marco Rubio signed an intergovernmental agreement on civil nuclear cooperation with Hungary on February 16, 2026. The ceremony, held in Budapest, highlighted the close diplomatic rapport between the two nations, with Rubio emphasizing the strength of the partnership and the shared commitment to mutual prosperity and security.
Rubio described the relationship between the United States and Hungary as “as close as I can possibly imagine it being,” underscoring the historic and strategic ties that have been nurtured under the leadership of President Donald Trump and Hungarian Prime Minister Viktor Orbán. The agreement aims to facilitate peaceful nuclear energy development, enhance technological exchange, and promote safe, secure, and responsible use of nuclear materials.
“Your success is our success,” Rubio remarked during the signing ceremony, signaling the United States’ dedication to supporting Hungary’s economic growth and national stability. He further noted that should Hungary face financial challenges or obstacles to development, he is confident that President Trump would be actively engaged in exploring ways to assist.
The pact aligns with broader U.S. efforts to strengthen civil nuclear cooperation globally, consistent with guidelines established by the U.S. Department of Energy’s Office of Nuclear Energy. Such agreements are vital for advancing clean energy initiatives and ensuring that nuclear technology is used safely and securely.
Hungary’s Prime Minister Viktor Orbán, who was present at the ceremony, has been a prominent figure in European politics, advocating for national sovereignty and economic resilience amid shifting geopolitical landscapes. His government has prioritized energy diversification and modernization, making the nuclear cooperation agreement a cornerstone of Hungary’s long-term energy strategy.
The agreement also reflects the United States’ broader foreign policy objectives to deepen alliances in Central Europe, a region of increasing strategic importance. The U.S. Department of State has consistently highlighted Hungary as a key partner in promoting regional stability and shared democratic values.
Experts note that civil nuclear cooperation agreements such as this one facilitate not only energy development but also enhance nonproliferation efforts by establishing robust frameworks for oversight and accountability. The U.S. Nuclear Regulatory Commission plays a critical role in ensuring that nuclear materials are handled in accordance with international safety standards.
As global energy demands evolve and the urgency of addressing climate change intensifies, nuclear power remains a pivotal component of many countries’ energy portfolios. The U.S.-Hungary agreement represents a mutual commitment to harnessing nuclear energy responsibly while strengthening bilateral ties.
Secretary Rubio’s visit and the signing ceremony come at a time when the United States is actively engaging with allies to secure energy independence and counterbalance geopolitical challenges. The partnership with Hungary exemplifies the diplomatic and technical cooperation necessary to meet these complex goals.
