Walid Muallem said during a news conference in Baghdad that he had told his counterpart Hoshyar Zebari and Iraqi Prime Minister Nuri al-Maliki of the decision during the previously unannounced visit to Baghdad.
Muallem told reporters that President Bashar al-Assad's regime had agreed "in principle to participate in the international conference which is supposed to be convened in Geneva".
"We think... That the international conference represents a good opportunity for a political solution to the crisis in Syria."
