LONDON: President Barack Obama and his South Korean counterpart agree that the international community must unite around "a stern, united response" if North Korea proceeds with a planned rocket launch.

Obama and South Korean President Lee Myung-bak (lee myuhng bahk) met Thursday on the sidelines of the London G-20 summit on the world economy.

The South Korean presidential office issued a statement after the Obama-Lee meeting saying they had agreed "to work together in the course of" a joint reaction to the launch.

North Korea says it will send a communications satellite into orbit on a multistage rocket in the coming days. The U.S., South Korea and Japan call the plan a cover for testing long-range missile technology.
