Chinese relatives of passengers on missing Malaysia Airlines Flight MH370 have continued to demand answers since arriving in Malaysia over a week ago.

Jing Hongxu, relative of an MH370 victim, says no one from the Malaysian government had met with them after they went to the prime minister's office to get more information and a meeting with Malaysia Airlines officials had yielded nothing.

"We just want to ask the Malaysian government questions, all of our questions, but nobody can meet us. But this time we got nothing answer, we ask a lot of questions, but no answers."

Twenty-one family members and next of kin flew to Kuala Lumpur last week to demand more information after Malaysia's Civil Aviation Authority officially declared the plane had crashed in an accident.

Flight MH370 disappeared on 8 March 2014 on the way from Kuala Lumpur to Beijing.
