Analysts feel that North Korea's rejection on March 30, 2014 of international condemnation of earlier missile tests could suggest it is preparing to conduct another missile test. This is reinforced by Pyongyang's declaration of a "no sail" zone in waters near Wonsan.
US agencies assess that North Korea will conduct a long range missile test flight rather than an underground fourth nuclear test. North Korea recently disclosed it had deployed six of its new KN-08 missiles near Wonsan, which has been confirmed by satellite imagery.
