Special report: Iran Nuclear Crisis

A senior Iranian official said on Tuesday that his country adopts proactive diplomacy to help restore Iraq's security, the official IRNA news agency reported.

Ali Akbar Velayati, advisor to Iran's Supreme Leader Ayatollah Ali Khamenei on political affairs, said that Iran showed goodwill during negotiations with Iraqi and U.S. officials in Baghdad.

His remarks came one day after Iranian and U.S. ambassadors met in Baghdad to discuss Iraq's security during the first high-level direct official talks between the arch-foes in 27 years.

Velayati said that Monday's meeting was a token of understanding shown by Iran in helping remove ambiguities and a call for the change of the arrogant literature from certain U.S. officials against Iran.

U.S. Ambassador to Iraq Ryan Crocker on Monday urged Iran to stop supporting Iraq's militia in the rare but "positive" meeting with his Iranian counterpart in the Iraqi capital.

Crocker said at a news conference that his talks with Iranian Ambassador to Iraq Hassan Kazemi Qomi was "positive" and "business-like" and both parties agreed for a stable Iraq.

The ice-breaking talks, held in the residency of Iraqi Prime Minister Nuri al-Maliki, is the first for the United States and Iran since the diplomatic relations of the two countries have been severed for more than a quarter century.

Analysts said though the high-profile talks achieved no breakthrough as what U.S. and Iranian officials expected, it marked a shift from isolation to engagement in the U.S. policy toward Iran on Iraqi issues.
