A news report says a Chinese tycoon whose company said he was assisting an official investigation after he disappeared for a day last week has emerged to speak at a corporate meeting.

The newspaper China Business News and other outlets said Guo Guangchang, chairman of the Fosun conglomerate that owns France's Club Med, spoke Monday at the previously scheduled Fosun event.

It said Guo talked about the need to expand globally but gave no indication whether he mentioned the investigation.

Fosun suspended trading of its shares after a business magazine reported it was unable to contact Guo. The company issued a statement later Friday saying Guo was assisting in an unspecified investigation.
