Vietnam haven't published a whitepaper detailing specifically what islands it wants to claim, just the general area of the spratly and paracel islands. Sometimes it refers to the islands near the Phillipines as "west" or "south" of the spratly islands.

Anyways, thank you with your polite and civil response. To be honest I didn't expected any substantial discussion to come out from such a heated dispute, and I understand you have probably dealed with a bunch of Vietnamese people who has no idea about de facto control and such. I made this relation in order to help data consumers in Vietnam has an easier time complying with the authorities and that is essential for OSM Vietnam community growth in general.
