An investigation by Mongolia into the 1971 plane crash that killed Lin Biao, China’s No. 2 leader at the time, concluded that the cause was unlikely to have been a lack of fuel as China says, records obtained by Kyodo News show.
Meanwhile, a Mongolian source knowledgeable about the investigation told Kyodo that the team of investigators had concluded that a struggle had probably taken place on board as Lin tried to flee to the Soviet Union after the failure of his attempted coup.
