The billionaire co-founder and chairman of China’s HNA Group died Tuesday July 3 2018 in an accident while on a business trip in Provence in southern France, the company said today. Wang Jian was 57. Mr. Wang’s death makes HNA’s current goal of simplifying its complex corporate ownership more difficult. He owned a 15 percent stake in the conglomerate, helped create the complex web of ownership, and was the point person for many of the company’s business dealings. Wang had a degree in airline management from the Civil Aviation University of China and an MBA from the Maastricht School of Management in the Netherlands.
