Russia’s President Vladimir Putin will meet with Mahmoud Ahmadinejad in Beijing on June 6 or June 7 before world powers gather in Moscow to discuss Iran’s nuclear program.

The meeting with Ahmadinejad will allow Putin to “feel the heat surrounding the Iranian problem and how this issue is perceived in Tehran,” Yuri Ushakov, a former ambassador to the U.S. who advises Putin on foreign policy, told reporters in Moscow yesterday.

The Ahmadinejad meeting foreshadows an international round of talks about Iran’s atomic program in Moscow on June 18-19, the third attempt in three months to address global concerns that Iran is developing atomic weapons.
