Beijing (CNN) An oil tanker burning in the East China Sea has sunk a week after it collided with another vessel, according to Chinese state media. The Panama-registered Sanchi tanker sank Sunday after an explosion rocked it and sent flames shooting up, CCTV reported. Chinese maritime authorities launched a search and rescue operation for the 30 Iranian and two Bangladeshi crew aboard the Sanchi. Iran joined the international rescue effort led by China, sending a rescue team of its own, including Iranian navy commandos on speed boats. But the teams couldn't get close to the burning tanker due to the heat.
