The Government of Afghanistan signed a deal with China National Petroleum Corporation (CNPC) for the development of oil blocks in the Amu Darya basin, a project expected to earn billions of dollars over two decades; the deal covers drilling and a refinery in the northern provinces of Sar-e Pol and Faryab and is the first international oil production agreement entered into by the Afghan government for several decades.[8] Production of the Afghan oil began in October 2012, which was expected to increase to 1 million barrels per year in 2013.[9]
