China and the US have agreed to co-ordinate their response to any “potential provocation” if North Korea goes ahead with a planned rocket launch, the White House says.
North Korea says the long-range rocket will carry a satellite. The US says any launch would violate UN resolutions and be a missile test.
US President Barack Obama and Chinese President Hu Jintao met on the margins of a nuclear summit in South Korea.
The launch is scheduled for April.
