Organizers of the World Economic Forum in Davos say they have revoked an invitation to a delegation from North Korea in the wake of the secretive Communist country's latest nuclear test.

The WEF says in a statement Wednesday that an invitation was extended to North Korea in the autumn "in view of positive signs coming out of the couuntry." The North Koreans accepted the invitation.

The statement said, however, that following the nuclear test, the delegation would be subject to "existing and possible forthcoming sanctions."

The WEF said: "Given the recent discussions, we cannot maintain the invitation we have issued last year."

The statement added that a delegation would still be welcome if North Korea "acts as a responsible and responsive member of the international community." It did not elaborate.
