BANGKOK, Jan. 28 (Xinhua) -- The annual multi-national military exercise codenamed Cobra Gold will be held in Thailand's eastern region next month, said a Thai navy officer on Sunday.

Thailand, the United States and several other Asian countries will have their military personnel join in the annual military exercise on Feb. 13-23 in eastern Thai provinces including Sattahip naval base in Chonburi, U-tapao naval air base in Rayong, Chachoengsao and Chanthaburi, said the navy officer on condition of anonymity.

Military personnel from dozens of countries will either participate in or observe Cobra Gold 2018 which will primarily feature the command post exercise, the field training exercise and the humanitarian aid and disaster relief, he said.

Cobra Gold, first held in 1982, is considered the biggest military exercise in the Asia-Pacific region.
