BEIJING - China's government says it is sending three warships to join the search for possible pieces of a missing Malaysia Airlines plane in the southern Indian Ocean.

The National Maritime Search and Rescue Center said Friday the three ships are en route to the area where a satellite image showed two large objects floating about 2,300 kilometres west of Australia. It gave no indication when they might arrive at the remote site.

The centre says a fourth Chinese vessel, the icebreaker Snow Dragon, is in the western Australian port of Perth after a voyage to the Antarctica in January and might join the search.
