The Annual Meeting in Davos remains the foremost creative force for engaging the worlds top leaders in collaborative activities focused on shaping the global, regional and industry agendas.

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

More than 40 heads of state and government will attend next week's World Economic Forum (WEF) in Davos, which this year is focused on "mastering the fourth Industrial Revolution," organisers said on Wednesday.
