Obama arrived at Belfast this morning. After his Belfast speech he will attend a two-day summit of the Group of Eight industrial economies.

Today, he'll meet on the sidelines of the summit with Russian President Vladimir Putin. Topics for the two leaders range from Syria to arms control. Russia has criticized Obama's decision to arm Syrian rebels and has dismissed U.S. claims that President Bashar Assad's regime has used chemical weapons against Syrians.

Russia is a member of the G-8. So are Canada, Japan, Britain, France, Italy and Germany.
