HANOI, Vietnam, Rajab 28, 1435, May 27, 2014, SPA -- Vietnam and China traded accusations Tuesday over who was the aggressor in a clash that led to the sinking of a Vietnamese fishing boat in the South China Sea, sharpening tensions already dangerously high after China moved an oil rig into the disputed waters, AP reported. Hanoi accused a Chinese vessel of ramming the wooden Vietnamese boat Monday then fleeing the scene. Beijing said the Vietnamese boat was trying to get close to the oil rig, rammed into one of its vessels, and then sank. The crew was rescued. The clash occurred around 30 kilometers (18 miles) south-southwest of the large oil rig that China deployed on May 1 in waters both nations claim. --SPA 13:25 LOCAL TIME 10:25 GMT www.spa.gov.sa/w
