The International Conference on Asian and Pacific Coasts (APAC) is an international conference to promote academic and technical exchange on coastal related studies that include coastal engineering and coastal environmental problems, among the Asian and Pacific countries/regions. APAC is jointly supported by the Chinese Ocean Engineering Society (COES), the Coastal Engineering Committee of the Japan Society of Civil Engineers (JSCE), and the Korean Society of Coastal and Ocean Engineers (KSCOE). A wide range of organizations from Asian and Pacific countries/regions are its active participants or sponsors. The Conference is held once every two years.
The first conference was held in Dalian, China in 2001 by the name of Asian and Pacific Coastal Engineering (APACE). To reflect a broader scope, the conference was renamed to Asian and Pacific Coasts (APAC) and it was subsequently held every two years in different countries including Japan (2004), Korea (2005), China (2007), Singapore (2009), Hongkong (2011), Indonesia (2013), India (2015), Philippines (2017) and Vietnam (2019).
