Taiwanese leader Ma Ying-jeou’s visit to Ba Binh (Taiping) island seriously violated Vietnam’s sovereignty, the foreign ministry spokesman said Thursday.
The visit ran counter to Taiwan's recent statements which expressed hope to contribute to maintaining peace and stability in the East Sea, spokesman Le Hai Binh said, using the Vietnamese name of the South China Sea.
Vietnam has "full legal foundation and historical evidence asserting her indisputable sovereignty" over the Truong Sa (Spratly) and Hoang Sa (Paracel) archipelagoes, he said. Ba Binh island is part of Truong Sa.
The Taiwanese leader's visit "accelerated tensions and complicate the situation in the East Sea," he said.
Vietnam "resolutely opposes and requests" Chinese Taiwan to immediately end its violations of Vietnam’s sovereignty, as well as not to repeat similar actions, he said.
