China, Japan, and the Governance of Space: prospects for competition and cooperation

China and Japan are among the world’s top space powers, with significant technical competence in both conventional and ‘newspace’ capabilities. Since the early 1990s, each country has also taken a keen interest in shaping the governance of outer space activities. But they have done so in remarkably different ways, calling into question Asian states’ supposed preferences for soft and informal institutions. Japan has led the Asia-Pacific Regional Space Agency Forum, involving both state and nonstate participants, which is guided by a set of principles. China has opted for a high-profile formal intergovernmental design, the Asia-Pacific Space Cooperation Organization, with a Convention and all the trappings of a formal organizational structure. This article assesses the activities of China and Japan in the new space race, discusses how and why the design of their space governance differs, and reflects on prospects for competition and cooperation.
