Greece has formally joined Pax Silica, a US-led initiative aimed at strengthening cooperation among trusted partners in AI, energy, semiconductors, critical minerals and secure technology supply chains.
The declaration was signed on Tuesday, June 23 at the US State Department by Greece’s ambassador to Washington, Antonis Alexandridis, and US Under Secretary of State for Economic Growth, Energy and the Environment Jacob Helberg.
The move brings Athens into a growing US-backed framework that treats advanced technology, computing power, raw materials, and energy infrastructure as central pillars of economic and national security.
Greece enters Pax Silica as AI supply chains become security priority
Greece joined Pax Silica alongside the European Commission, Germany, and the Netherlands, expanding the initiative’s European footprint as Washington seeks to establish a wider coalition around the technologies that power the AI economy. The initiative already includes Japan, South Korea, Singapore, Australia, Israel, the United Kingdom, Qatar, the United Arab Emirates, Sweden, Finland and India.
At its core, Pax Silica is focused on the creation of more resilient supply chains for semiconductors and critical minerals, while reducing Western dependence on China in sectors now viewed as strategically essential.
From energy diplomacy to AI infrastructure
The decision follows the US-Greece Economic Security Declaration signed last November during the P-TEC energy summit at the Zappeion Hall in Athens. That declaration later helped shape Pax Silica, connecting energy security, investment protection, trusted technology, and supply-chain resilience under a broader strategic framework.
Greek officials view participation in the initiative as a way to deepen cooperation with the United States in areas where economic policy, technology, and national security increasingly overlap. Pax Silica also gives Athens a place in Washington’s planning for secure supply chains at a time when semiconductors, critical minerals, digital infrastructure, and computing capacity are becoming key elements of global competition.
Critical minerals and cybersecurity
Athens expects Pax Silica to support Greece’s access to critical minerals, which are essential for both the green transition and the digital economy. These materials are used in technologies ranging from clean energy systems and batteries to advanced electronics and AI infrastructure.
The issue is not limited to access to raw materials. Athens also views trusted US technology, including hardware and software, as part of the effort to protect national digital infrastructure. In that sense, Pax Silica is not only about industrial cooperation. It is also about cybersecurity, trusted suppliers, and the resilience of systems that support public services, research, energy, and business activity.
Greece ties Pax Silica to AI projects in Kozani and Lavrio
Greece’s interest in the initiative is linked to major technology and infrastructure projects already under development. One of the most vital is the planned data center in Kozani by PPC, the Public Power Corporation, Greece’s largest electricity company. The project is expected to begin with a first phase of 300 MW and is being developed in cooperation with a major US technology group active in cloud infrastructure and services. The investment could position Western Macedonia, a region historically linked to lignite and power generation, as a hub for high-performance digital infrastructure.
Another key project is DAEDALUS, Greece’s national supercomputer in Lavrio, which will operate with Nvidia equipment. The system is expected to expand the country’s computing capacity and support large-scale research in artificial intelligence, data analysis, and advanced scientific applications.
The next major Pax Silica summit is scheduled to take place in Washington on June 25 and 26. It will be bringing together representatives of participating countries, along with companies from the fields of artificial intelligence, semiconductors, energy, and advanced technologies.
