Because of the activity of MEND fighters oil companies operating in Nigeria since 2006 have reduced average daily oil production by more than 20 per cent. This has allowed Angola to catch up with Nigeria for the amount of oil production, denying her the title of the largest oil producer in Africa.

The militants of the organization repeatedly attacked facilities owned by foreign oil companies, as well as killed and the hostages were seized in their staff.

In response to the actions of the government militia called on their supporters to arms and demanded that foreign oil companies as soon as possible to curtail their activities in the region.
