The two presidents met before today's round of talks at the G20 summit in London. Yesterday Obama told Chinese president Hu Jintao that the US would seek UN Security Council punishment if North Korea launches the rocket. Earlier, Obama said that South Korea is one of "America's closest allies and greatest friends" and he lauded Lee's leadership. Obama said the two would discuss a range of issues, including defense and "peace and stability in the Korean Peninsula." The president has now arrived at the G20 conference center, although he was forced to take a car after his helicopter was grounded by the London fog.
