奥巴马普京北京峰会短暂会晤

U.S. President Barack Obama and Russian President Vladimir Putin have met briefly on the sidelines of a conference in Beijing, covering a few of the key global issues on which their governments do not agree.

Mr. Obama and Mr. Putin flanked Chinese President Xi Jinping and exchanged comments about the room as leaders walked into the venue for Tuesday's Asia-Pacific summit.

But away from the main talks, the White House said U.S. and Russian leaders met three times throughout the day for a total of about 15 to 20 minutes.

U.S. National Security Council spokeswoman Bernadette Meehan said the topics included Iran, Syria and Ukraine, but did not provide additional details.
