Hainggyi Island (Burmese: ဟိုင်းကြီးကျွန်း, also spelt Haigyi Island or Hainggyikyun) is a town on the island of Hainggyi Island[2] located at the mouth of the Pathein River (formerly Bassein River)[3] in the Ayeyarwady Region of south-west Myanmar. It is the primary town within Hainggyikyun Subtownship within Ngapudaw Township in the Pathein District.
The town has an area of 5.44mi2.[4]
The Pammawaddy Regional Command of the Myanmar Navy is headquartered in Hainggyi Island. The naval base used to host a few PLA personnel from china.[5] According to Andrew Selth, claims of a massive PLA base on Hainggyi Island is plainly incorrect and gained popularity because of hysterical quotations by commentators.[6]
