OK --let's get it straight here--Which countries are messing with Sudan's internal affairs ?
In recent years, a significant amount of foreign-based oil drilling has begun in Southern Sudan, raising the land's geopolitical profile. Khartoum has broken much of the Sudan into blocks with about 85% of the oil coming from the South. Blocks 1, 2, and 4 are controlled by the largest overseas consortium, the Greater Nile Petroleum Operating Company (GNPOC). GNPOC is composed of the following players: CNPC, the People's Republic of China, with a 40% stake, Petronas (Malaysia), with 30%, ONGC India, with 25%, and Sudapet of the central Sudan government with 5%[citation needed].
The other producing blocks in the South are blocks 3 and 7 in Eastern Upper Nile. These blocks are controlled by Petrodar which is 41% owned by CNPC of China, 40% by Petronas, 8% by Sudapet, 5% by Gulf Petroleum and 5% by Al Thani[citation needed].
Another major block in the South, called Block B by Khartoum, is claimed by several players. Total of France was awarded the concession for the 90,000 square kilometre block in the 1980s but has since done limited work invoking "force majeure". Various elements of the SPLM handed out the block or parts thereof to other parties. Several of these pre-Naivasha deals were revoked when the SPLM came to power. One company, Jarch Management Group, Ltd., claims that the Government of Southern Sudan has since accepted its pre-CPA contracts
