Sudanese officials have opened a new oil pipeline expected to raise the country's output to at least 500,000 barrels of oil per day.
Government ministers attended a launch ceremony for the pipeline in the town of Fallouj on Monday.
The 1,400 kilometer pipeline will carry oil from wells in Sudan's southeast to Port Sudan on the Red Sea.
Revenue will be split between the northern and southern governments, which signed a wealth-sharing agreement as part of the peace deal that ended Sudan's north-south civil war last year.
The pipeline is run by Petrodar, a conglomerate owned mainly by China's National Petroleum Corporation and Malaysia's Petronas. Companies in Dubai and Sudan and another Chinese firm own smaller shares.
China is the world's second-largest energy consumer after the United States, and has become a major investor in Sudan as it seeks foreign sources of oil.
