The White House is considering new sanctions against Syria amid a crackdown by that country’s government against pro-democracy demonstrators… The administration imposed a similar strategy with Libya, said Richard Sawaya, director of USA Engage, which promotes alternatives to unilateral U.S. sanctions. He also noted that Iran sanctions legislation approved by Congress in 2010 targeted individuals in Iran… Few if any U.S. companies are still doing business with Syria, which could put a limit on the effect of any U.S. sanctions, said Bill Reinsch, president of the National Foreign Trade Council. “For the most part, companies doing business there pretty much unilaterally decided to get out,” he said.
