WAPI (WLAN Authentication and Privacy Infrastructure) is the wireless local area network (WLAN) standard officially supported by the Chinese state government. WAPI was initiated in 2004. In 2006, however, the International Standards Organization (ISO) rejected the incorporation of WAPI as an international WLAN security standard in 2006. Instead, ISO supported the 802.11i security specification developed by the Institute of Electrical and Electronics Engineers (IEEE) as the default global standard. WAPI, however, continues to be used throughout the China telecommunications system, particularly at government agencies and contractors.
