In its East China Sea diplomacy, Taiwan has been creative and constructive. In August 2012, President Ma Ying-jeou proposed the East China Sea Peace Initiative (ECSPI) to manage rising tensions over the disputed islands known as the Diaoyutai Islands in Taiwan, the Senkaku Islands in Japan, and the Diaoyu Islands in Mainland China. The key elements of his initiative are self-restraint, shelving disputes, observing international law, pursuing a code of conduct, and jointly developing resources in the East China Sea.
