The co-founder and chairman of the giant Chinese conglomerate HNA Group has died in a fall in southern France, while touring the Provence region.

Wang Jian, 57, had climbed on a high parapet to take photographs in the picturesque village of Bonnieux when he fell, police said.

Rescue services in the region were unable to revive him.

Mr Wang helped turn HNA into one of the world's biggest companies, with assets in aviation, tourism and finance.

It has major stakes in Deutsche Bank, hotel chain Hilton and skyscrapers in London and employs more than 400,000 people worldwide.

The company is currently in the process of selling down some of its international assets in a bid to reduce its domestic debt built up during a rapid expansion in recent years.

The company, which turned its website grey in a gesture of mourning, said it had lost an "exceptionally gifted leader and role model, whose vision and values will continue to be a beacon for all who had the good fortune to know him".

How did he die?

Police are not treating his death as suspicious.

Mr Wang was among a party of about 10 tourists visiting Bonnieux, in the picturesque Luberon area, on Tuesday morning, the France Bleu news site reports.

He was near the village's upper church when he climbed onto a parapet at about 11:30 (09:30 GMT) to take pictures of the "superb panorama" offered by the Cedres forest, the site says.

Speaking through their own interpreter, Mr Wang's travelling companions told police it had been an accident.

A local police chief, Hubert Meriaux, was quoted as saying by Reuters news agency that Mr Wang had been trying to get his family to take a picture of him when he fell.

According to various sources, he fell between 12m (39ft) and 15m (49ft).

His widow was expected to arrive in the region on Wednesday, according to France Bleu.
