The country list (XML Output) from above URL contains Countries and Country groups (or) Regions. 

Q’s:

-          Why is the above URL returning both Countries and Country groups (or) regions? It should return the countries only.

-          Is there any webservice to get the country list by excluding the groups (or) regions?

-          Is there a flag in the XML output (from the above URL)  to determine the group (or) region?

-          Can we pass any parameter to the above URL to filter the Countries?

Unfortunately, there is not yet distiction between country or area in the web service result.

In UN Comtrade, all reporters are individual countries/areas (statistical areas) except EU-25 (country code 97). In the partner side, the only pre-aggreagated partner is World (code 0). It means that sum of all partners (except World) will be equal to partner World.
