Closer to home, China has made efforts to reduce tensions in parts of Asia; its relations with its Asian neighbors have become stable during the last decades of the 20th century. It has contributed to stability on the Korean Peninsula, cultivated a more cooperative relationship with members of the Association of Southeast Asian Nations (ASEAN) (Brunei, Cambodia, Burma, Indonesia, Laos, Malaysia, Philippines, Singapore, Thailand, Vietnam), and participated in the ASEAN Regional Forum. In 1997, the ASEAN member nations and China, South Korea and Japan agreed to hold yearly talks to further strengthen regional cooperation, the ASEAN Plus Three meetings. In 2005, the "ASEAN Plus Three" countries together with India, Australia and New Zealand held the inaugural East Asia Summit (EAS). Relations have improved with Vietnam since a border war was fought with the one-time close ally in 1979. A territorial dispute with its Southeast Asian neighbors over islands in the South China Sea remains unresolved, as does another dispute in the East China Sea with Japan. These conflicts have had a negative impact on China's reputation in many parts of the world.
