NO BREAKTHROUGH

Chinese marine police rescuers have found oil slicks in waters around the search site for a missing Malaysian plane and have sent samples to relevant authorities for analysis.

Samples were sent via proper channels on Monday at noon, according to a brief statement from China's marine police bureau.

However, the statement provided no detail on whether the samples will be sent back to China or to the nearest lab.

China called on Malaysia to accelerate the search for the flight.

"We hope Malaysia can fully understand China, especially the mood of the Chinese passengers' families and speed up investigation, search and rescue efforts," Foreign Ministry spokesman Qin Gang said at a daily news briefing.

"We hope Malaysia can make it clear as soon as possible," Qin said, while acknowledging the importance Malaysia attached to dealing with the incident and their sincerity to do all it could.

"The missing plane belongs to the Malaysian Airlines, so it is reasonable that the Malaysian side takes the major responsibility of the search and rescue work," Qin said.

So far, there's still no exact information about the location of the flight, according to Malaysian Airlines.
