It's the eleventh day of the search, but still no trace of the plane has been found.

On Tuesday, Malaysian ministers said they were working with 25 other countries and had narrowed the search area to two corridors. The northern corridor stretches from the border of Kazakhstan and Turkmenistan to Northern Thailand. While the southern corridor goes from Indonesia to the southern Indian Ocean.

Haixun 01 headed toward Singapore on Tuesday to join in the search for missing Malaysia Airlines flight MH370. The vessel is estimated to arrive in the waters near Singapore for supplies on Wednesday before dawn and will continue its way to help search for the jet in waters near the Sunda Strait.

China and Kazakhstan have taken the lead in analyzing radar data for the northern corridor. Australia and Indonesia are heading up efforts in the southern corridor, though China has also offered to deploy aircraft there.

Malaysian authorities say the focus is now on four tasks: gathering information from satellite surveillance, analyzing surveillance radar data, increasing air and surface search forces, and increasing the number of technical experts.

The Malaysian government has also asked all countries involved to examine their satellite data. And ASEAN leaders have been requested to provide more ships with deep ocean detection capabilities. The government also touched on the Aircraft Communication Adressing Reporting System, ACARS, which have been at the center of the plane's mysterious disappearance.
