A Role for China in Gulf of Guinea Piracy?

As piracy decreases in the Gulf of Aden, where China's PLA Navy has played a prominent role, it is increasing in West Africa's Gulf of Guinea.  The question arises whether China might join an effort to combat piracy, which is aimed at stealing resources rather than taking ships for ransom, in the Gulf of Guinea.  In an excellent analysis on 10 December 2013 in The National Interest titled "Piracy's Next Frontier: A Role for China in Gulf of Guinea Security?" Andrew S. Erickson and Austin M. Strange, both experts on piracy and China's effort to combat it, explain why China is less likely to engage in the Gulf of Guinea in the same way that it did in the Gulf of Aden.
