Mihai Razvan Ungureanu served as foreign minister from 2004 until April when he was forced to resign in April after he failed to inform Prime Minister Calin Tariceanu Popescu that two Romanians had been arrested in Iraq by U.S. troops.
Ungureanu, 39, is a historian by training and known for a pro-American stance. In 2005 he signed a 10-year agreement with U.S. Secretary of State Condoleezza Rice to set up U.S. bases on Romanian soil.
The post heading the Romanian Foreign Intelligence Service has been vacant since its former chief, journalist Claudiu Saftoiu, resigned in March after he alleged that the service had illegally tapped the telephones of Romanian and foreign suspects with permission from prosecutors, instead of a judge's warrant as required by law. He later retracted his statement.
Ungureanu's nomination must be approved by Parliament.
