Chinese billionaire Guo Guangchang is defending his company Fosun's multi-billion dollar shopping spree abroad — as it buys yet another foreign firm — amid greater government scrutiny on massive overseas deals.

Fosun "has always done two things: First, it has developed at an appropriate pace while reducing debt and improving its financial strength," Guo wrote in a letter to employees, state media reported. "I always believe that we are 'going out' so we can return better and we are consolidating our global resources so we can better develop in China."
