The Western Pacific Naval Symposium are a series of biennial meetings of the Pacific nations to discuss naval matters held on even numbered years. A WPNS workshop is held on odd numbered years in between the symposiums.
At the International Seapower Symposium in 1987 agreement was reached "to establish a forum where leaders of regional navies could meet to discuss cooperative initiatives". The first meeting was held in 1988.
At the 2014 WPNS, agreement was reached on the Code for Unplanned Encounters at Sea.
