Sourcing oil itself is the easy part, securing the shipping is the problem - You need to find available tankers first, and account for higher shipping rates and extended delivery time.
Even if You cold take one of those empty tankers idling in the gulf of Oman and reroute her to the Gulf of America, it would still take at least 3 months for the first shipment to get to East Asia.
Time for everyone who has oil under their feet to become independent, that will save lots of fuel.
