The decision comes as a surprise to many observers, as he missed last year's gathering of the world economic elite and is a known critic of globalist policies that dominate in the forum.
United States President Donald Trump plans to attend the World Economic Forum (WEF) in Davos, Switzerland later this month, his spokeswoman said on Tuesday.
The lone attendee from his coterie of advisers previous year was hedge fund manager Anthony Scaramucci, who later served briefly as Trump's communications director. A year before the consensus had been that he would not win the presidency.
During his election campaign President Trump had railed against globalisation in favour or an "America first" agenda, labelling Hillary Clinton, as "a globalist".
It is rare for American presidents to attend. Since becoming president, Trump has withdrawn from multinational trade agreements with Pacific Rim allies and Europeans and threatened to pull out of the North American Free Trade Agreement if talks with Mexico and Canada don't yield significant changes.
The annual conference, to be held January 23-26, has brought together worldwide leaders of nations, business and finance at the Alpine ski resort since 1971 to discuss global cooperation.
In an interview on Monday prior to the announcement, Harvard University professor Ken Rogoff identified Trump as a risk to the economic expansion. There's a randomness element that's hard to quantify.
Executives at the conference will welcome Trump's corporate tax cut and the regulatory slash his administration had enforced.
