Republicans on Thursday also asked for a review of Freeman’s relationship with China and Iran. Freeman has served on an international advisory board of the government-owned Chinese National Offshore Oil Company, according to a biography posted on Businessweek.com. The company signed a $16 billion agreement with Iran to develop one of its oil fields in 2007. The State Department has not determined whether that deal violates economic penalties placed on Iran in an attempt to curb its nuclear program, spokesman Noel Clay said. Questions about Freeman were referred to Blair’s spokeswoman, Wendy Morigi, who noted that Freeman has 30 days to identify and resolve potential financial conflicts of interest. Freeman was appointed last week. Freeman has stirred controversy on conservative blogs because of his sharp criticism of the Israeli government, the Iraq war and the Bush administration’s approach to fighting terrorism.
