Migration waves and terrorism to dominate Davos get-together

Europe's migrant crisis and devastating terror attacks will combine with the plunging oil price and China's economic slowdown to give the elite of the political and business worlds plenty to talk about when they gather in Davos from Jan. 18.

Over 40 heads of state and government will join chief executives, NGO leaders and Hollywood stars as they converge on a Swiss ski resort - transformed into a highly secure fortress for the occasion - for their annual attempt to try to plot a way through the world's complexities.

Vice President Joe Biden leads a heavyweight U.S. delegation that also includes Secretary of State John Kerry and Defense Secretary Ashton Carter. They will rub shoulders with far-left Greek Prime Minister Alexis Tsipras, who will lock horns once again with German Finance Minister Wolfgang Schaeuble in what promises to be an animated debate.

Argentina's President Mauricio Macri makes his first appearance at Davos since his election in November and will lay out his case for economic reform in a country with a turbulent recent past. Afghanistan's President Ashraf Ghani will seek understanding for his country's ongoing unrest and Nigerian President Muhammadu Buhari will face questions about his handling of the Boko Haram insurgency in Africa's most populous country.

Pressing the flesh with the invitees will be Oscar contender Leonardo DiCaprio, a long-time environmental campaigner, who will no doubt take the opportunity to remind the world leaders present to keep the commitments on climate warming they agreed in Paris in December.
