Kuala Lumpur: China and Malaysia vowed to continue the underwater search for the missing Malaysia Airlines flight MH370 “until it is found.”

“Both sides agreed to continue to work closely together in the sub-surface search operation for the missing flight in the southern Indian Ocean off the west coast of Australia,” a joint statement issued by the two countries said.

However, relatives of passengers aboard the tragic MH370 Malaysian Airlines flight have sought a new plan, after the search was deferred subsequently due to a new setback.

Tempers flared after the joint centre set up to oversee the search for the jetliner that vanished on March 8 said a robot submarine had found no trace of the plane in a section of the southern Indian Ocean where acoustic signals were detected.
