Beijing, Shawwal 18, 1433, Sep 5, 2012, SPA - The United States is disappointed by the failure of China and Russia to agree to tougher sanctions against Syria, US Secretary of State Hillary Clinton said Wednesday. "It is no secret that we've been disappointed with Russia's and China's actions blocking tougher UN Security Council resolutions, and we hope to continue to unite behind a real path forward to end the violence in Syria," Hillary Clinton told reporters. Diplomats were "discussing additional ways" to end the violence in Syria, she said following talks with Chinese Foreign Minister Yang Jiechi. "The best course of action remains to unite the United Nations Security Council," Hillary Clinton was quoted as saying by dpa. China and Russia, veto-holding permanent members of the Security Council, have blocked UN efforts to intervene in the 17-month conflict beyond the deployment of UN observers during a failed ceasefire plan launched in April. --SPA 12:13 LOCAL TIME 09:13 GMT www.spa.gov.sa/1027232
