The concept of an East Asian community emphasizes the importance of open regionalism, which means maintaining friendly ties with countries outside the region. This approach benefits East Asia by allowing trade and investment with other countries, as well as support from international institutions like the WTO. The presence of the U.S. military in the region also contributes to stability. By promoting openness, transparency, and inclusiveness, regional cooperation can help prevent fears of creating a closed economic bloc and benefit both East Asia and the international community.
