BEIJING - Relatives of the Chinese passengers aboard missing Malaysia Airlines flight MH370 have demanded China mount its own inquiry into the disappearance, a letter shows.
The document, sent to Beijing's special envoy in Kuala Lumpur, denounced Malaysia's handling of the search and asked the Chinese government to set up its own "investigation office".
News of the letter comes as a committee set up by relatives of the 153 Chinese passengers has begun discussions with lawyers about a potential lawsuit against Malaysia Airlines, a move that the family members have hotly debated among themselves.
"We question Malaysia's motivations in misleading and delaying so as to miss the best moment to find MH370," the relatives wrote in the letter to special envoy Zhang Yesui Thursday, blasting Kuala Lumpur's behaviour as "irresponsible" and "inhumane".
"We earnestly request that China establish an investigation office into MH370," the letter states, also urging "an effective communication system between the relatives and the government".
Beijing has urged Kuala Lumpur to include Chinese experts in its own investigation, but has not so far spoken of setting up its own inquiry into the flight.
