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.
SEASMA provides continuity in safety assessment and airspace monitoring of the responsible region (PDF, 136 KB).

b. Submit new Performance-based navigation (PBN) approvals without delay
c. Submit withdrawal of PBN approvals without delay
d. Submit lateral and longitudinal errors report at the end of every month (even if there were no errors that month)
e. Submit navigation error investigation form when there are reported LLDs and LLEs
f. Submit Traffic Sample Data (TSD) at the end of the year
