In December 2011, Afghanistan signed a deal with 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.
Former Tajik warlord Ismail Khan also fled to Faryab to reconstitute his forces following the Taliban takeover of Herat Province, but was betrayed by Uzbek warlord Abdul Malik Pahlawan.
Following a series of changing allegiances and falling out with Uzbek warlord Abdul Malik Pahlawan in 1997, the Taliban withdrew from the area, but in 1998 a contingent of 8,000 Taliban troops pressed through neighboring Faryab, seizing Abdul Rashid Dostum's headquarters in Sheberghan.
