Xihai'an also known as Qingdao West Coast is a district of Qingdao, Shandong, China, located southwest and west of the main urban area of the city on the western shore of Jiaozhou Bay. It was identical to Qingdao Economic and Technological Development Zone (QETDZ) (simplified Chinese: 青岛经济技术开发区; traditional Chinese: 青島經濟技術開發區; pinyin: Qīngdǎo Jīngjì Jìshù Kāifāqū) which was launched in 1985 after the zone was merged with Huangdao District and set up the Free Trade Zone in 1992. In December 2012, neighbouring Jiaonan City was merged into Huangdao.
