At Davos, Iran is center-stage, North Korea has been disinvited for nuclear saber-rattling, and World Economic Forum founder Klaus Schwab says he's worried about Europe's future, the fallout of plunging oil prices and gaping inequality worldwide.

The 77-year-old chief of the world's most recognized annual economic confab tells The Associated Press in an interview Monday that his event fell in line with international condemnation of North Korea's nuclear test this month when it disinvited its foreign minister. WEF had been working hard to bring North Koreans to the 45-year-old annual gathering at the highest level since the 1980s.

After this weekend's landmark end to vast international sanctions against Iran, Foreign Minister Jarid Zarif is set to be a headliner at the Alpine resort as the mostly business event opens Wednesday.
