The Chinese can orchestrate what happens in Cameroon directly with the Cam Govt if they want to.
Cam Govt just let the Mbalam convention expire. Pay out the Sundance subsidiary in Cameroon (Cam Iron) and take control of the project.
Sundance chances of resurrecting this project are Zero. Everything points to a company poised and priced to fail.
Don't look to ANS or WAPRC to save them. The Chinese do not need any of them and they are playing the long game and in no hurry.
I would do exactly the same...
