The court in China's southern island of Hainan, where the group is based, said the vote had been conducted in accordance with the country's bankruptcy laws. HNA was placed in bankruptcy administration in February and a working group was created by the Hainan government to address the company's liquidity problems. HNA will receive strategic investment of 38 billion yuan ($5.88 billion) after its restructuring, which will go to 11 of its entities including its flagship carrier Hainan Airlines.
