the legislation "exacts indirect imperial tribute" from African states, noting AGOA contains a clause requiring participating African countries not to oppose American foreign policy. Some allege that AGOA is in contradiction with WTO rules. Furthermore, it is seen as a one-sided agreement as there was little African involvement in its preparation. AGOA has also been criticized for being "dominated by oil and raw materials" After the enactment of AGOA, "exports have increased by more than 500 per cent from around $8.2 billion then to $54 billion in 2011, although about 90 per cent of these are natural resources, mainly oil," wrote Andualem Sisay.
