China seized control of Anbang Insurance for political reason.

http://www.bbc.com/news/business-43164788

The chairman of Anbang Insurance was Wu XiaoHui.  This man is very well politically connected because he is the grandson-in-law of Deng XiaoPing.  The major shareholders of Anbang are also politically connected and involved Jiang MianHeng (Son of Jiang Zeming), Zhou YongKang (Jiang's henchman), Zhu Rongji's henchman, etc.

Basically, Jiang Zeming had tremendous power over Anbang and Anbang embarked on aggressive international acquisitions under the instructions of Jiang so that Anbang could be used to disrupt China's economy in the future.  Please read our previous postings to get an understanding on Jiang's plan to disrupt China's economy.
