More than 60 heads of state and government and hundreds of business leaders are coming to Switzerland to discuss the biggest global challenges during the World Economic Forum’s annual gathering next week, ranging from Israeli President Isaac Herzog to Ukrainian President Volodymyr Zelenskyy.

The likes of U.S. Secretary of State Antony Blinken, Chinese Premier Li Qiang, EU Commission President Ursula von der Leyen, French President Emmanuel Macron, U.N. Secretary-General Antonio Guterres and many others will descend on the Alpine ski resort town of Davos on Jan. 15-19, organizers said Tuesday.

Attendees have their work cut out for them with two major wars — the Israel-Hamas conflict and Russia’s invasion of Ukraine — plus problems like climate change, major disruptions to trade in the Red Sea, a weak global economy and misinformation powered by rapidly advancing artificial intelligence in a major election year.
