MOSCOW?Russia again warned the United States against withdrawing from the Anti-Ballistic Missile Treaty, saying it would upset global stability at a troubled time.

“It is especially dangerous in the current difficult international situation,” the Foreign Ministry said Thursday after talks between Deputy Foreign Minister Georgy Mamedov and U.S. Undersecretary of State John Bolton.

Their meeting was to prepare for U.S. Secretary of State Colin Powell’s visit beginning on Sunday. Overall relations have warmed because of Russia’s support for the U.S.-led war on terrorism.

“Russia again noted the negative consequences for international stability in case the United States decides to unilaterally withdraw from the 1972 ABM Treaty, which is supported by an absolute majority of nations,” the statement said.
