From the Sudan Tribune:

"Obviously the oil companies are deeply complicit. Attacks by Janjaweed, often with aerial support from Sudan government forces, have cleared the way for pipelines and drilling. Oil company roads and bridges are used by government troops to carry the genocide into more remote communities in Darfur. And it is an unhappy fact of recent history that violence, disorder, and corruption generally accompany the exploitation of oil in undeveloped nations. Oil revenues do not translate into schools and hospitals for the people; they translate into arms and Swiss bank accounts for the elite. Sudan, the largest country in Africa, and one of the poorest, is a case in point"

In this recent article, it states that Britain and other countries are busy signing contracts for Sudan's oil while the genocide is continuing.
