Fosun International’s Chairman Guo Guangchang has traveled to the United States, two company executives said on Friday, suggesting that Chinese authorities were not restricting the movement of the billionaire. Last Sunday, Fosun’s President Wang Qunbin said Guo was helping police with an investigation that mostly concerned his “personal affairs”. The investigation had sparked investor concern over Fosun, one of China’s most aggressive global dealmakers with stakes in French resort chain Club Med, Britain’s Thomas Cook Group (TCG.L) and iconic U.S. building One Chase Manhattan Plaza.
