The Vietnamese government has complained to Facebook after discovering the platform’s ad manager tool provided a map marking disputed South China Sea islands as Chinese, state media reports.
A spokesperson from Vietnam’s Ministry of Information and Communications told the Tuoi Tre newspaper the complaint was lodged when it was shown that the Spratly and Paracel archipelagoes were marked as Chinese territory on Facebook’s Boost Page feature.
The Paracels, previously controlled by the old South Vietnamese government, were invaded by China in 1974. Control of the Spratlys is divided among Vietnam, China and the Philippines, all of which claim the entire island chain.
Vietnam and China most recently fought over the Spratly islands in 1988, when a naval battle at Johnson Reef left 64 Vietnamese sailors dead and the reef in Chinese hands.
Facebook acknowledged it had used a “wrong” map and would fix the issue, reported Tuoi Tre.
China claims almost all the South China Sea, including waters claimed by Vietnam, the Philippines, Taiwan, Malaysia and Brunei.
