Oil-for-food, country by country
First, the global network: Congress Probes Routing of Funds To Suspect Firms

The number of companies involved was relatively small, a few dozen out of the more than 3,000 contractors tapped by Saddam under U.N. terms that let him choose, subject to U.N. veto, his own business partners. Among several of this band, the rerouted payments were copious. In some cases, they form a latticework of disturbing associations. These include such U.N.-approved dealers as Al Wasel & Babel General Trading, based in Dubai, United Arab Emirates, which sold $384 million of goods to Saddam under oil for food.
