Collision may have left small oil spill

A possible small oil spill has been discovered near where two ships collided in the East China Sea five days ago, as the blaze on an oil tanker continued to rage.

The Panama-registered tanker Sanchi, carrying 136,000 metric tons of highly flammable condensate oil, or natural gasoline, collided with a Hong Kong-registered bulk freighter around 8 pm on Saturday about 160 nautical miles east of Shanghai.

It has drifted southeast since the collision, and was about 240 nautical miles from the mouth of the Yangtze River as of 6 am on Thursday, according to the State Oceanic Administration.
