U.S. policy toward the Central Asian states has aimed at facilitating their cooperation with U.S. and NATO stabilization efforts in Afghanistan and their efforts to combat terrorism; proliferation; and trafficking in arms, drugs, and persons. Other U.S. objectives have included promoting free markets, democratization, human rights, energy development, and the forging of East-West and Central Asia-South Asia trade links. Such policies aim to help the states become what various U.S. administrations have considered to be responsible members of the international community rather than to degenerate into xenophobic, extremist, and anti-Western regimes that contribute to wider regional conflict and instability.
