SHANGHAI—Billionaire Guo Guangchang appeared early Monday at an interior celebration at the organization he controls, Fosun Team, in Shanghai, according to a particular person familiar with the predicament.
It wasn’t distinct whether the look alerts an end to Mr. Guo’s dealings with Chinese authorities. On Friday, Fosun stated he was assisting authorities with an unspecified investigation, and on Sunday stated it was a personal matter that didn’t include the company.
That assistance manufactured him unreachable late previous week. In China, authorities have broad powers to detain witnesses as effectively as suspects associated to potential wrongdoing.
It wasn’t obvious what Mr. Guo explained at Monday’s celebration. Images of him standing at a lectern during the inside conferences at a Shanghai resort circulated on Chinese social media.
The business did not update a regulatory statement issued late Friday signed by Mr. Guo that explained he was assisting authorities but was obtainable to function on main concerns involving Fosun, a big private investment conglomerate that he controls.
Shares in the group’s major detailed unit, Fosun International Ltd. , plunged when investing opened in Hong Kong. But a Fosun bond that matures in 2020 rallied about 5% to 98 cents on the greenback Monday, following a plunge Friday amid speculation about Mr. Guo’s whereabouts.
