North Korea says a summit between the US and South Korean presidents is a prelude to war against the North.
A spokesman for the Committee for the Peaceful Reunification of Korea today called President Park Geun-hye's otherwise widely praised visit to Washington a "despicable sycophantic trip to please her master."
President Barack Obama and Park warned Pyongyang on Tuesday against nuclear provocations. Pyongyang conducted its third nuclear test in February and has since issued a string of war threats.
The North Korean spokesman says Pyongyang is watching "with patience" to see whether Park changes what it considers a hostile position.
Park and Obama say they are open to dialogue if Pyongyang moves toward nuclear dismantlement.
