The Gulf Cooperation Council said Syria had rejected Arab attempts to solve the crisis and end 11 months of bloodshed.
The US closed its embassy in Syria on Monday, and several European countries have recalled their ambassadors.
The moves came as Syrian government forces continued their fierce assault on the restive city of Homs, and Russian officials visited Damascus.
Russian Foreign Minister Sergei Lavrov called for a solution to the crisis based on Arab League initiatives, days after Russia and China vetoed a UN resolution on Syria.
After meeting Mr Lavrov, Syrian media quoted President Bashar al-Assad as saying he was willing to co-operate with "any efforts towards stability".
