Pax Silica Declaration

We affirm our shared commitment to advance mutual prosperity, technological progress, and economic security for our peoples.

We recognize that a reliable supply chain is indispensable to our mutual economic security. We also recognize that artificial intelligence (AI) represents a transformative force for our long-term prosperity and that trustworthy systems are essential to safeguarding our mutual security and prosperity. 

We recognize that the technological revolution in AI is accelerating, increasingly reorganizing the world economy, and reshaping global supply chains. We believe that economic value and growth will flow through and across all levels of the global AI supply chain, driving historic opportunity and demand for energy, critical minerals, manufacturing, technological hardware, infrastructure, and new markets not yet invented.

In this spirit, we declare our shared vision to deepen our economic partnership through shared efforts on investment security practices, infrastructure, and incentives.

We encourage efforts to partner on strategic stacks of the global technology supply chain, including, but not limited to, software applications and platforms, frontier foundation models, information connectivity and network infrastructure, compute and semiconductors, advanced manufacturing, transportation logistics, minerals refining and processing, and energy.

We believe in mobilizing the immense creative and financial power of private industry and entrepreneurship to make our citizens more prosperous, our nations stronger, and our supply chains more secure. We seek scalable approaches and solutions to supply chain security by mobilizing the complementary industrial and technological strengths of strategic companies and firms from our respective economies.

We support the promotion of a shared and trusted ecosystem of AI developers and vendors to renew legacy industries and unlock new markets and services for the lasting prosperity of our peoples.

We believe that true economic security requires reducing excessive dependencies and forging new connections with reliable partners and suppliers committed to fair market practices. At the same time, we will endeavor to provide access to trusted partners to the full stack of technological advancements that are shaping the AI economy.

We understand the importance of addressing non-market practices that undermine innovation and fair competition. We believe that coordination is essential to protect private investment from the market distortions of overcapacity and unfair dumping practices, and to preserve a level playing field for innovation and growth. We understand the importance of cooperation on the enforcement of our respective policies to protect sensitive technologies and critical infrastructure from undue access, influence, or control. 

In this spirit, we intend to further strengthen economic and national security cooperation, including taking complementary actions as appropriate to address non-market policies and practices and cooperating on investment security.

We seek to build and deploy rusted information networks, including information and communication technology systems, fiberoptic cables, and data centers.

Through this cooperation, we pursue a comprehensive economic partnership to build an economic security order based on trust, technological complementarity, shared interests, and a shared commitment to a more prosperous future.
