Russia is a long-term ally of the Assad regime and maintains a naval base in the country. Last month a UN security council move to bring sanctions against Syria was blocked by Russia and China.The Arab League announced on Saturday that Syria's membership would be suspended and that it would also impose economic and political sanctions. Syria responded by announcing it would boycott next month's Arab Games in Qatar but, in an apparent concession, also invited Arab League observers to visit the country before the suspension is due to take effect on Wednesday.
