  The following excerpt was removed from the original version of the text.
  
  “One example of a global company that has ‘put on its China hat’ is the telecommunications company Alcatel-Lucent. Since 2002, Alcatel-Lucent has operated in China through its subsidiary Alcatel Shanghai Bell (ASB), in which the Chinese government has a minority stake.

The EXIM Bank has granted the company US$63.3m in funding to aid its overseas expansion. In Africa, ASB has won deals in countries such as Ghana, Angola, and Nigeria.”
