The East Asian Defense Initiative, or simply the EADI, is a military alliance located in East Asia.

Following the Invasion of Taiwan, the Sino-Japanese Cold War will emerge between the People's Republic of China and the State of Japan, regardless of the war's outcome. Since China faced Taiwan alone against the Pacific Defense Treaty Organization, it will establish the EADI to counter Japan and its allies.

In the following years up to the Great Asian War, China will try to diminish Japanese influence in East and Southeast Asia, aiming to sway regional nations into its alliance.

The EADI often backs pro-Chinese governments in Asia, in an attempt to diminish the EADI's power projection over Asia.

The EADI trades with EADI aligned and Neutral nations
