Mr Hussein also defended his Government over growing Chinese criticism about the handling of the disaster.
He said until the debris is found the one question Chinese relatives are asking cannot be answered.
And in a veiled reference to the Chinese reaction, where there have been angry scenes and water bottles hurled at Malaysian officials and protest marches, Mr Hussein said many nations had lost loved ones.
“Time will heal emotions that are running high. We fully understand but for the Chinese families they must also understand that we in Malaysia also lost loved ones. There are so many nations that lost loved ones.
“I have seen some images coming from Australia, very rational, understanding that this is a global effort, not blaming directly ... because we are co-ordinating something that is unprecedented,” Mr Hussein said.
He was referring to the Australian families of passengers meeting yesterday with Prime Minister Abbott.
