"Lifting U.S. sanctions at this time will merely strengthen Robert Mugabe and the military circle around him."

"It is a mistake to judge the lack of progress as a failure of sanctions per se."

"It is the policy of the United States to support the people of Zimbabwe in their struggle to effect peaceful, democratic change, achieve broad-based and equitable economic growth, and restore the rule..."

"Sanctions should remain in place on Zimbabwe for the time being."
