Earlier, our correspondent Wei Lynn Tang in Shanghai gave us the latest updates.

WEI LYNN TANG SHANGHAI "Latest we have remains the same, 3 dead bodies found. Let's have a listen to an expert's explanation."

XUE ZHOU COSCO SHIPPING "The next most important job is fire fighting. Unlike fire fighting work on land, we first spray water on the hull of the tanker to cool it down, in order to prevent combustion and explosions. Then we spray foam over the fire. It works pretty well. Dry ice is another fire extinguishing agent we use to fight fires caused by burning oil. But it only works when used inside the cabin. We are 160 kilometers southeast of Shanghai. The tanker has drifted again, fifty to sixty kilometers southeast, which adds a lot of pressure for our rescue work."
