BEIJING (AFP) - A huge oil spill off the Chinese coast has now contaminated an area around six times the size of Singapore, state media reported Friday, as the government said it may seek compensation for the leak. The spill from the oil field, which the US' ConocoPhillips operates with China's state-run oil giant CNOOC, has polluted a total area of almost 4,250 square km, govt figures showed. The figures, which were announced on the State Oceanic Administration website earlier this week but only reported on Friday, were almost five times the size of the 840-square-kilometre area previously reported.
