Food and fuel supplies sent to North Korea have been halted, not to force North Korea to stop missile tests or participate in peace talks, but to return the Chinese trains the aid was carried in on. In the last few weeks, the North Koreans have just kept the trains, sending the Chinese crews back across the border. North Korea just ignores Chinese demands that the trains be returned, and insists that the trains are part of the aid program.

Ray comma Light: If the North Koreans appear to make no sense, that's because they don't. Put simply, when their unworkable economic policies don't work, the North Koreans just conjure up new, and equally unworkable, plans. The Chinese have tried to talk the North Koreans out of these pointless fantasies, and for their trouble they have their trains stolen. How do you negotiate under these conditions? No one knows.
