Two cargo ships collided Sunday off China's eastern coast, leaving 20 crew members missing, an official said. Efforts were underway to find the missing sailors, said a man surnamed Wang who answered the phone at the office of the marine police in Zhejiang province's city of Taizhou. Wang did not give details, but the official Xinhua News Agency said a 17,061-ton Chinese vessel collided with a Cambodian ship at about 4 a.m., causing the 6,500-ton Cambodian vessel to sink immediately, according to AP. Nineteen of the missing sailors are Chinese while the remaining one is Indian, Xinhua said. Xinhua also said local authorities have dispatched two rescue boats to the scene, and that the cause of the collision was under investigation. -- SPA
