I'm a little puzzled by the Chinese statement that they've 'cleared' all the Chinese pax.
From NY Times:
“China has conducted a thorough investigation, and to date we have not found any signs that any passengers on board the plane participated in destruction or terror attacks,” Mr. Huang said at a news briefing in Kuala Lumpur for Chinese reporters, according to a summary on the website of the state-run People’s Daily newspaper.
Wasn't there one passenger travelling on a Chinese passport, where the passport owner was alive and well and had never lost or mislaid his passport? So do the Chinese government know who that passenger really was, in order to absolve him from suspicion?
