Greece and the United States have signed a broad joint declaration on economic security in Athens, capping off a major transatlantic energy summit.
The pact focuses on strengthening supply chains, countering "coercive dependencies," and advancing trusted technology, particularly artificial intelligence (AI).
The agreement concluded the 6th Transatlantic Partnership for Energy Cooperation (P-TEC) conference, which also resulted in landmark deals for U.S. liquefied natural gas (LNG) transport and new exploratory gas drilling in the Ionian Sea.
The declaration was signed by U.S. Under Secretary of State for Economic Affairs Jacob Helberg, new U.S. Ambassador to Greece Kimberly Guilfoyle, and Greek Deputy Foreign Minister Haris Theoharis.
In statements afterward, Mr. Helberg said U.S. allies are seeking to secure their supply chains while "seizing the economic opportunities of the AI revolution."
He described America as an "indispensable partner" ready to help its friends pursue a "better tomorrow."
"Through this landmark Declaration, the United States and Greece will pursue flagship projects that will define the AI economy for decades,” Mr. Helberg said.
According to the joint statement, both sides affirmed their commitment to "jointly pursue multilayered partnerships" that strengthen shared economic security.
The pact calls for advancing trustworthy AI systems and mobilizing private-sector leadership to deliver high-quality jobs.
It also explicitly aims to protect sensitive technologies and critical infrastructure from access or control by "countries of concern."
The agreement includes provisions to build trusted information networks, such as fiber-optic cables and data centers, and to coordinate responses to state-backed overcapacity and unfair dumping, while fostering an open investment climate.
