President Trump will join fellow billionaires and heads of state at the World Economic Forum’s annual meeting in Davos, Switzerland, even as his nationalist ally, British Prime Minister Boris Johnson, refuses to attend and will not let his ministers go.

The Davos meeting, scheduled for Jan. 21 to 24, is criticized for its elite deal-making and cosmopolitanism, which critics say undermine the sovereignty of nations. American presidents have typically avoided the event.
