President Lee Myung-bak will hold a summit with U.S. President Barack Obama on the sidelines of the G20 Summit scheduled to open in Toronto, Canada, on Saturday.

A high-ranking U.S. government official said, on the condition of anonymity, that Obama will have separate meetings with the South Korean president, Chinese President Hu Jintao and Japanese Prime Minister Naoto Kan during the G20 meeting.

The official added that the U.S. president is also scheduled to meet with British Prime Minister David Cameron for the first time since Cameron took office in May.
