Malaysia has no intention of hiding information on Flight MH370 from families and the authorities, Malaysian Prime Minister Najib Razak said on Tuesday.
"Our priority, after confirming that the incident happened in the Indian Ocean, is to focus in this area," Mr Najib told Parliament.
He added that the black box is the only way to find the answers as to what happened to the Malaysia Airlines aircraft, adding that "no theories can be substantiated yet".
His Australian counterpart Tony Abbott called him on Tuesday morning, and again offered all assistance.
"This is not the time to politicise the issue, it's time for us to show our solidarity with families of those on board," Mr Najib said.
On Monday night, he announced that MH370 was lost in the southern Indian Ocean and all on board feared dead.
