In a statement Tuesday explaining a decision last week to curtail military ties, Russia's mission to NATO said the freeze would halt military exercises, exchanges of military delegations, visits by high-level NATO officials to Moscow and stopovers by NATO warships in Russian ports.

Russia said a joint committee on peacekeeping would be suspended, as well as an agreement that would have allowed NATO troops to cross Russian territory and negotiations on having Russian military cargo planes work with NATO.

However, the Russians said they were ready to "continue cooperation in fighting international terrorism, drug trafficking, civil emergency planning and arms control."

NATO last Thursday announced that Russia had decided to halt military cooperation. Western officials played down the significance of the decision, saying allied nations had effectively already decided to cut back cooperation programs in response to Russia's continued military presence in Georgia.

They said the freeze was unlikely to affect NATO's mission in Afghanistan, since the alliance had not yet started to use supply routes through Russia under an April agreement.
