US Secretary of State Hilary Clinton yesterday called on European countries as well as India and China to step up their pressure on the Syrian regime. She said ‘what we really need to do to put the pressure on Assad is to sanction the oil and gas industry.’ Not being a major economic partner of Syria, the US has been working to drum up international support for sanctions against Syria’s oil and gas sector. The sectors provide as much as a third of the regime’s revenues. It is reported that Washington is also encouraging energy companies trading with Syria to cease. Clinton said Washington had been "very clear" in its statements about Assad's loss of legitimacy but the "real trick" was to convince Syria’s trading partners to do more.
