East Asia Economic Caucus
The East Asia Economic Caucus (EAEC) or East Asia Economic Group (EAEG) was a regional free trade zone (FTA) proposed in 1997 by Malaysian Prime Minister Mahathir Mohamad and encompasses most nations of East and Southeast Asia (ESEA). However, Japan at the time refused participation due to the exclusion of the United States, which at the time had tariffs on each other, has an economy too deeply interlinked through trade, and was still reeling from the effects of the Japanese asset price bubble.
