Several dozen Chinese relatives of passengers on Flight 370 have arrived in Malaysia to demand to meet top officials for more information about what happened to the airliner that has been missing for more than three weeks.

Two-thirds of the 227 passengers aboard the Malaysia Airlines plane that disappeared March 8 en route to Beijing from Kuala Lumpur were Chinese, and Beijing has urged Malaysia to be more open about the investigation.

Malaysia Airlines commercial director Hugh Dunleavy says 29 Chinese family members flew to Kuala Lumpur on Sunday. They were ushered through a VIP area at the airport onto two large buses that drove them to a hotel about half an hour away.
