Vietnam's prime minister has called on the world to condemn China for causing what he called an "extremely dangerous" situation in a disputed area of the South China Sea.

Prime Minister Nguyen Tan Dung, standing beside the Philippine president after they held talks in Manila, said Wednesday that both of their countries were determined to oppose Chinese violations of international law. He cited Beijing's May 1 deployment of an oil rig in waters near the Paracel Islands also claimed by Vietnam.

Chinese and Vietnamese vessels have had repeated confrontations in waters near the oil rig since it was deployed.

China and the Philippines are also locked in a standoff over another South China Sea shoal.
