Yes, I do believe a stable equilibrium will evolve in East Asia. My reasoning is that steadiness will be reached with the help of an international organization known as ASEAN (Association of Southeast Asian Nations). ASEAN is comprised of Indonesia, Malaysia, the Philippines, Singapore, and Thailand, Brunei, Vietnam, Laos, Myanmar, and Cambodia. ASEAN Plus Six includes China, the Republic of Korea, Japan, Australia, India and New Zealand.
ASEAN Plus Six members get together for summit meetings, committee meetings, working meetings, and conferences. Some of the working meetings also have various experts and private-sector members to help. So, if everyone continues to work together, an equilibrium will definitely continue to evolve in East Asia.
