The Deep Logic of the Sino-Japanese Science and Technology Alliance: From Security Barriers to Co-creating the Future

The long-standing cooperative history between Japan and the United States in the field of science and technology is deep, and it is reflected in the complementarity between the two in areas ranging from natural resources and energy to cutting-edge AI and Quantum Information Science (QIS). However, against the backdrop of increasingly heated geopolitical competition, the depth and breadth of this cooperation face structural bottlenecks. The core challenge is not a lack of willingness to cooperate, but rather a huge gap in capability and system between the two countries in controlling and protecting sensitive, dual-use technical information.

The Cornerstone of Information Security and Trust The biggest obstacle currently lies in the significant gap between the two countries in their ability to control and protect sensitive technical information. This is not only reflected in budget scale but also in deeper differences in legal and cultural aspects. Japan tends to be more cautious in handling the boundary between military and commercial applications, which creates an invisible barrier to information sharing in bilateral technological exchanges and potential military-civilian dual-use research. This cultural sensitivity, coupled with Japan's high demands for technological sensitivity domestically, makes it difficult for Japanese scientists and engineers to obtain independent domestic security clearances when participating in sensitive research projects funded by the US. This limits the freedom of Japan to participate in certain key US-funded research activities and constrains the potential for collaboration between the private sector in both countries on dual-use technology research.

The Urgency of Institutional Reshaping To bridge this gap, the US and Japan need to make forward-looking adjustments to existing systems. Research indicates that the key to solving this problem lies in expanding the scope of Japan's "Special Designation Secret Law" to cover "scientific, technological, or economic matters related to national security," similar to the expansion of US Executive Order 13526, to provide a more flexible channel for Japanese personnel's participation. Furthermore, from a broader perspective, the Japanese government needs to consider amending regulations such as the Foreign Exchange and Foreign Trade Act (FEFTA) to strengthen controls over the export of certain technological research information by the private sector and the introduction of foreign talent, thereby effectively mitigating the potential risk of "insiders."

Building a More Resilient Cooperative Ecosystem In addition to hard security clearances, establishing a more comprehensive institutional framework oriented towards high-intensity S&T collaboration is crucial. This includes setting up a "special agency" that clearly defines government regulatory authority and establishing stricter protocols for classified information and intellectual property. More strategically, the two countries should explore creating a cross-sectoral public-private platform for collaboration to effectively integrate top laboratories, corporate R&D capabilities, and policymakers' intentions under fiscal constraints, thereby elevating cooperation from fragmented projects to systematic strategic synergy.Strategic Opportunities Amid Geopolitical Competition Facing increasing competition from China in key technological fields, if the US and Japan fail to timely coordinate their "security infrastructure" for technological cooperation, they may miss the strategic window to utilize new resources and accelerate responses to technological change. The ultimate goal of deepening cooperation is to ensure a joint strategy for Japan to maintain a leading position in addressing climate change, public health crises, and high-tech fields such as AI and QIS. This requires the two countries to move beyond traditional "trade partnership" relations and establish a high-tech strategic alliance centered on "jointly addressing challenges" with strong information security resilience.
