The South East Asia Safety Monitoring Agency (SEASMA) was established by CAAS in 2007 to assume the duties and responsibilities of the En-route Monitoring Agency (EMA) for the South China Sea Region. This was approved by the Asia/Pacific Air Navigation Planning and Implementation Regional Group (APANPIRG), a group set up by the International Civil Aviation Organization, to develop air navigation in the region.

As an EMA, SEASMA supports the implementation of horizontal separation minima (a set of requirements on the minimum distance between two aircraft), and monitors such operations in the airspace.
