The Soviet Union collapses in 1991, creating several new nations in Central Asia. Major US oil companies, including ExxonMobil, Texaco, Unocal, BP Amoco, Shell, and Enron, directly invest billions in these Central Asian nations, bribing heads of state to secure equity rights in the huge oil reserves in these regions. The oil companies commit to $35 billion in future direct investments in Kazakhstan. It is believed at the time that these oil fields will have an estimated $6 trillion potential value. US companies own approximately 75 percent of the rights. These companies, however, face the problem of having to pay exorbitant prices to Russia for use of the Russian pipelines to get the oil out.
