Asian Co-Prosperity Sphere

Created in 2022, the Asian Co-Prosperity Sphere (ACPS) was an alliance between China, the Hong Kong Collective and the recently combined Korean states.[1]


During 2023, the ACPS threatened hostilities with the Western Alliance over the inclusion of Japan into its organization. The ACPS instituted a naval blockade of Japan, with the Western Alliance airlifting supplies to the Japanese people. This caused the Japanese to side with the Western Alliance, but intense diplomatic efforts between the sides ultimately ended with the creation of the Osaka Agreement in 2024.[1]
