DHAKA: Relatives of the Chinese passengers on the missing Malaysia Airlines flight have threatened a hunger strike if the Malaysian authorities fail to provide more accurate information.

Families vented their anger at a meeting with the airline in Beijing, reported BBC.

Officials in Malaysia say they are trying to narrow the search area, which now covers about 2.24m square nautical miles (7.68m sq km).

Flight MH370 went missing on 8 March with 239 people on board.

Some 25 countries are involved in looking for the plane.

A total of 153 Chinese nationals were on board the missing aircraft, which was flying from Kuala Lumpur to Beijing.

China`s state media has been criticising the Malaysian operation.

Some Chinese relatives have said they believe the Malaysian authorities are holding information back and have demanded more clarity.

After a meeting with officials from Malaysia Airlines on Tuesday, families held a vote on organising a hunger strike.

"What we want is the truth," said one woman.

"Don`t let the passengers become the victims of a political fight."

Malaysian authorities say that finding the missing plane is still their priority

Ahmad Jauhari Yahy, chief executive of Malaysia Airlines, told a news conference on Monday that the airline was doing everything it could for the families.

Meanwhile, following speculation about the pilot`s links to Malaysian opposition leader Anwar Ibrahim, Malaysian Transport Minister Hishammuddin Hussein has said: "The search for flight MH370 is bigger than politics."

Captain Zaharie Shah was a supporter of the jailed politician.

Hishammuddin praised the international response to the search efforts and said teams were continuing to search two vast air corridors north and south of the plane`s last known location.

He added that the Malaysian authorities still believed the disappearance was a result of "deliberate action" on the plane.
