• Advancing pro-innovation AI policy frameworks and initiatives to support the adoption of a U.S. and Japan-led AI technology ecosystem;
• Promoting exports across the full stack of U.S. and Japanese AI infrastructure, hardware, models, software, applications, and related standards;
• Partnering to ensure the rigorous enforcement of existing protection measures, strengthen protection measures related to critical and sensitive technologies, and enhance supply chain resilience for the AI tech stack;
• Promoting mutual understanding of guidelines and frameworks for AI development and adoption from the respective Participants, with the goal of harmonizing practices as applicable to encourage interoperability;
• Advancing and refocusing the partnership between the U.S. Center for AI Standards and Innovation and the Japan AI Safety Institute towards a shared mission to promote AI innovation by fostering a secure and trustworthy AI ecosystem, including through working towards best practices in metrology for AI and industry standards development, improving understanding of both advanced AI models and sector-specific applications to drive continued AI adoption; and
• Promoting education, innovation, and technology for children to flourish in the digital era and preparing future generations for the workplace of tomorrow.

Trusted Technology Leadership
The Participants intend to enhance longstanding collaboration on key technologies and practices to enable technology leadership in the global arena, including:

• Research Security
  Recognizing the importance of shared research security goals across critical and emerging technology research and development, the Participants intend to deepen collaboration to protect their technologies and their people. The Participants intend to collaborate on research security and identify and mitigate threats to the research enterprise including through supporting capacity building for universities, research organizations, and industry; and collaborating with allies and partners to share similarly rigorous practices to facilitate a trusted ecosystem of innovation.
• Advanced Radio Access Networks, Beyond 5G/6G, and Connectivity
  Expanding their partnership in telecommunications innovation and supply chain resilience, the Participants intend to collaborate on building a trusted, interoperable supply chain, using advancements such as Open RAN and AI-RAN, through a partnership between the U.S. National Telecommunications and Information Administration and Japan's Ministry of Internal Affairs and Communications. Participants also intend to collaborate on all-photonics networks and quantum networks, and to enable joint research and development in Beyond 5G/6G-relevant technologies through the U.S. National Science Foundation and Japan's National Institute of Information and Communications Technology, and other relevant agencies. This work is intended to be supported by joint efforts in standards bodies and in close partnership with industry, including in open testbeds, to shape global telecommunications standards with the Participants' shared priorities and accelerate trusted technology solutions to market. Recognizing Japan's critical role as a connectivity hub between North America and Asia, the Participants intend to expand ongoing collaboration on submarine cables in the Indo-Pacific region.
• Securing Pharmaceutical and Biotechnology Supply Chains
  Highlighting the need to secure their mutual pharmaceutical and biotechnology supply chains, intellectual property, and innovation ecosystem, the Participants intend to accelerate progress towards the identification and remediation of vulnerabilities. The Participants intend to collaborate on supply chain security throughout all phases of development and across academic, government, and industry stakeholders, including contract research organizations and contract development and manufacturing organizations, to support resilient and healthy economies.
• Quantum Information Science and Technology (QIST)
  Recognizing the universe of possibilities that quantum technologies unlock, the Participants intend to collaborate through leading quantum institutions and national laboratories to assess quantum performance, develop quantum algorithms, overcome challenges for quantum technologies in real-world environments, and enable scientific discovery. The Participants also intend to support the development of the next generation of scientists and engineers. These activities are expected to be supported by aligning efforts in securing technology and supply chains to build a trusted ecosystem for the research, development, and adoption of new quantum technologies.
• Unlocking the Promise of Fusion Energy
  Appreciating the potential for fusion technologies to deliver safe, resilient, and abundant energy, the Participants intend to work together to facilitate a world-leading fusion industrial ecosystem. Areas of collaboration include supply chains for magnets and high-power components, fusion fuel cycle and blanket integration systems, neutronics modeling, and fusion materials. Participants intend to collaborate on fusion research and development, including the JT-60SA test facility, with the goal of supporting the commercial development and deployment of fusion reactors.
• Space
  Recognizing that research and development investments in space, including building capacity for human missions to the Moon and Mars, contribute to civilian mission needs, the Participants intend to continue their strong partnership in civil space and on aeronautics, science, and human exploration. Areas of collaboration include the International Space Station, future Artemis lunar surface exploration missions, and supporting enhancement of commercial space. The Participants intend to encourage further collaborative efforts to mitigate and remediate orbital debris and improve global coordination on space situational awareness.
