Paris (CNN) -- U.S. Secretary of State Hillary Clinton lambasted Russia and China on Friday for blocking efforts to topple Syrian President Bashar al-Assad, who has lost a key general to defection. Speaking at the Friends of Syria conference in Paris, Clinton called on Russia and China to "get off the sidelines" and accused them of "standing up for" al-Assad's regime. She urged the other 100 or so nations and organizations represented at the summit to "make it clear that Russia and China will pay a price" for that position. "I ask you to reach out to Russia and China and not only ask but demand that they get off the sidelines," she said. "I don't think Russia and China believe they are paying any price at all, nothing at all, for standing with (the) Assad regime."
