We will continue to fully co-operate with the authorities in this matter.”More: Glaxo and the peril of doing business in ChinaThe action signals China’s plans to take aggressive action against corruption by foreign executives. The country has recently taken a tougher stance on corruption by its own political leaders and local executives, but corruption remains a huge problem.Along with Reilly, who left Glaxo in July 2013, Chinese officials accused fellow executives Zhang Guowei and Zhao Hongyan, of bribing officials in Beijing and Shanhai, Xinhua said. An additional 46 others have been implicated in the case, which began last June.Gao said that Glaxo also had tried to disrupt the law enforcement investigation. It’s unclear what kind of punishment Reilly faces or when he will be formally indicted, if at all.
