In the setting of strong growing global economy, energy demand is becoming more and more urgent, and traditional energy sources, such as coal, petroleum, shale gas... are increasingly exhausted, the gas hydrate (GH) is defined as new energy source to replace fossil fuels in the future.

GH normally exists in a stable status in 500 m water depth corresponding to the hydrostatic pressure greater 50 atm. GH stability zone (GHSZ) exists in the depth of several hundred metres below sea floor at the continental slope. Many maritime countries around the world have special interest and appropriate investment for research, investigation and assessment of this potential resource type.

According to the United States Geological Survey assessment, Việt Nam has average potential of GH among Asian countries including (in descending order): Philippines, Sri Lanka, Malaysia, Việt Nam, Japan, China and Pakistan. This article will give a brief overview on GH resource potential of Vietnamese East Sea and orientation for research, assessment and investigation of GH and suggest orientations of exploitation of GH in the future .
