US, Japan Open Pax Silica Era for AI Supply Chains
Japan Becomes First Partner in Pax Silica Push
Washington: Japan will become the first and only country to sign a joint preamble with the United States ahead of the Pax Silica Declaration, marking a deliberate elevation of Japan’s role in a sweeping effort to reorganise the global technology supply chain. The signing in Washington, D.C. today, taking place on the eve of the Pax Silica Summit, is being positioned by both governments as the earliest and most pivotal step in a project designed to bind together the economies that underpin the world’s artificial intelligence infrastructure. By agreeing to jointly author the preamble, Tokyo and Washington are establishing the political architecture on which a broader coalition of participating nations will build when they sign the full Declaration the following day. No other country is included in this initial act, making Japan’s position uniquely consequential in shaping the initiative’s scope, language, and intent.
The preamble stresses a shared assumption that economic security and national security now operate as a single, interdependent concept. It frames the bilateral understanding that supply chain resilience, private investment, and technology standards are no longer peripheral considerations but the central drivers of geopolitical stability. Under Secretary of State for Economic Affairs Jacob Helberg and Japanese Ambassador to the United States Shigeo Yamada will sign the document, with Deputy Secretary of State Christopher Landau underscoring in his remarks that the initiative aligns with President Donald J. Trump’s call for a new era of economic statecraft. For Japan, which sits at the centre of semiconductor tooling, speciality materials, and advanced manufacturing, the signing formalises a strategic function it has long performed informally. For the United States, it secures a partner whose corporations and industrial capabilities occupy irreplaceable positions in the global AI hardware ecosystem.
The broader Pax Silica initiative extends far beyond bilateral coordination. It is conceived as a U.S.-led strategic framework to build a secure and innovation-driven silicon supply chain encompassing critical minerals, refined materials, advanced manufacturing, semiconductors, compute infrastructure, and logistics. The selection of participating countries for the inaugural summit—Japan, the Republic of Korea, Singapore, the Netherlands, the United Kingdom, Israel, the United Arab Emirates, and Australia—reflects a deliberate effort to assemble nations that host the companies and investors powering the global AI economy. These countries collectively represent essential nodes for silicon production, chip fabrication, networking systems, data centre construction, high-demand AI compute operations, and the industrial and financial capabilities that enable them. Canada and the European Union, joining later discussions at the summit, extend this network and underscore the initiative’s ambition to bring together virtually every major advanced technology jurisdiction.
The United States describes Pax Silica as a response to an emerging consensus across partner nations that the speed and scale of AI adoption have reshaped the economics of national power. The initiative’s framing documents identify several risks: coercive dependencies in mineral supply chains, single points of failure in semiconductor manufacturing, accelerating energy and materials demand driven by AI compute, and vulnerabilities within global information infrastructure. They cite partner nations’ increasing demand for deeper technology cooperation with Washington and the shared recognition that trustworthy systems are now a prerequisite for economic growth and security. The references to a “new economic security paradigm” signal an effort to formalise cooperation across industrial, digital, manufacturing, and mineral domains that historically operated in separate policy spaces.
The name Pax Silica reflects the initiative’s broader ambitions. Drawing on the Latin term for peace and stability and on the material foundation of semiconductor production, it positions the effort as a geopolitical framework rather than a technical agreement. The concept treats silicon, compute, minerals, and energy as shared strategic assets that must be protected and jointly developed. This makes the U.S.–Japan preamble significant not only for its symbolism but for the operational logic it establishes: a bilateral commitment that precedes multilateral expansion and sets the tone for how the broader grouping will define access, investment, standards, and security practices.
Once the summit begins, the full Pax Silica Declaration will be signed by Japan, the United States, Israel, Australia, Singapore, and the Republic of Korea, with additional signatories expected afterwards. Later in the day, a larger group that includes the Netherlands, the United Arab Emirates, Canada, and the European Union will join consultations on supply chain security and trusted technology ecosystems. These discussions aim to outline coordinated approaches to connectivity infrastructure, semiconductor production, advanced manufacturing, logistics networks, mineral refining and processing, and energy systems capable of absorbing political and market disruptions. It will also be the first time that countries collectively frame compute capacity, silicon production, minerals, and energy as interlocking strategic assets requiring coordinated protection.
The Declaration sets out shared principles that partner countries intend to operationalise. It acknowledges that AI is reorganising the global economy and that economic value will increasingly flow through every layer of the AI supply chain. It calls for collaboration across all segments of the technology stack, including software platforms, frontier foundation models, network infrastructure, mineral extraction and processing, fabrication, and transportation. It highlights the need to reduce coercive dependencies, protect sensitive technologies, and coordinate policy enforcement against non-market practices that undermine competition or distort investment. It seeks to mobilise private industry by encouraging joint ventures, strategic co-investments, and the development of trusted ecosystems for data centres, fibre-optic systems, communication networks, and AI developers. It commits partner countries to pursue fair market practices, ensure access for trusted partners to the full stack of technological advancements shaping the AI economy, and address risks posed by overcapacity and unfair dumping by state-backed actors.
The operational phase begins immediately after the summit. Under Secretary Helberg has instructed U.S. diplomats in Washington and at overseas missions to identify infrastructure projects aligned with the initiative and to coordinate economic security practices with partner governments. This directive, which extends across State Department headquarters and all global posts, signals a shift from conceptual planning to the identification of concrete projects involving compute clusters, semiconductor capacity, mineral-processing infrastructure, data networks, and energy systems required to support AI-driven growth.
Japan’s role remains foundational throughout the process. By becoming the first signatory to the joint preamble and the earliest partner in articulating the Declaration’s intent, Tokyo becomes the anchor around which the United States organises the initiative’s diplomatic, industrial, and technological dimensions. Pax Silica places Japan at the centre of a global attempt to restructure the systems that will define the AI-driven economy, giving the country a strategic position in an era where silicon, compute, minerals, and energy are emerging as the principal determinants of geopolitical stability and economic security.
