Kuala Lumpur - The search for missing Malaysia Airlines flightMH370 intensified Tuesday over two huge arcs of territory north and south of where the plane last made contact.
China began searching north-western parts of its territory in areas along the possible northern corridor, said the Chinese ambassador in Kuala Lumpur, Huang Huikang, according to the Xinhua news agency.
He added that background checks on all the passengers had found no evidence of links to terrorism or involvement in a possible hijack, Xinhua said.
Australia was leading the search on the southern corridor. The New Zealand government said Tuesday it was sending an air force plane to Australia at the request of the Malaysian government to help with the international operation to find the plane.
