According to earlier media reports, Abbott, who is on an official visit to China, said he was "very confident" that the signals detected are from the missing flight.

In a luncheon in Shanghai, he said the information does not mean that the debris of the plane can be found.

Australia, along with China and other countries involved, will try every effort to continue the search, according to sources who quoted Abbott at the luncheon site.

The plane disappeared on March 8 while flying from Kuala Lumpur to Beijing with 239 people on board, including 154 Chinese passengers.

The plane's black box, or flight recorder, could be used to solve the mystery of why the plane veered so far off course.
