The law, which terminates agreements with Australia, Denmark, Italy, Spain, South Korea, the Netherlands, Norway, New Zealand, Poland, Turkey and France, was passed by an overwhelming majority in parliament on March 6.
Bakiyev signed a decree to close the Manas airbase on February 20. Kyrgyzstan officially notified Washington about the termination of the agreement on a U.S. military presence at the base, and gave it 180 days to withdraw some 1,200 personnel, aircraft and other equipment.
The Kyrgyz parliament said the termination of the founding agreement with the U.S. made agreements with other countries "senseless."
In late March, Kyrgyz officials dismissed reports that the country was considering allowing U.S. troops to remain at the Manas airbase.
The base, staffed mainly by U.S. Air Force personnel, had been used since 2001 to support NATO operations in nearby Afghanistan.
Bakiyev linked the decision to Washington's refusal to pay more for the base and to the conduct of U.S. military personnel, including the killing of a Kyrgyz national by a U.S. soldier in December 2006.
Kyrgyz officials have rejected any connection between the decision and a recent Russian financial aid package under which Russia will write off Kyrgyzstan's $180 million debt and grant the country a $2 billion soft loan and $150 million in financial assistance. Moscow has likewise denied any link.
