LONDON -- South Korea's president is leaving the Group of 20 summit with U.S. support for "stern action" against North Korea's planned rocket launch, observers say.
A major item on South Korean President Lee Myung-bak's agenda for the meeting was to secure support for a joint call on North Korea to scrap its rocket-launch plans, South Korea's Yonhap news agency reported Friday.
Lee and U.S. President Barack Obama agreed to seek U.N.-imposed sanctions against North Korea if Pyongyang goes ahead with its planned launch.
Yonhap says Lee's greatest accomplishment at the summit came when the summit participants agreed to a set of measures to fight trade and financial protectionism.
A statement issued by the participants said they wouldn't "repeat the historic mistakes of protectionism of previous eras."
Lee is a strong advocate of open markets since nearly 70 percent of his country's economy depends on trade with other nations.
