The government has accepted the arms control obligations of the former Soviet Union, acceded to the Nuclear Non-Proliferation Treaty (as a non-nuclear state), and supported an active program by the U.S. Defense Threat Reduction Agency (DTRA) in western Uzbekistan (Nukus and Vozrozhdeniye Island). The Government of Uzbekistan spends about 3.7% of GDP on the military but has received a growing infusion of Foreign Military Financing (FMF) and other security assistance funds since 1998.
