During his election campaign President Trump had railed against globalisation in favour or an "America first" agenda, labelling Hillary Clinton, as "a globalist".
Anxiety over Trump's "America First" agenda dominated the conversation at the World Economic Forum a year ago, though the incoming USA administration eschewed sending any official representatives.
Sarah Sanders said Trump was excited to attend the tony forum in the Swiss Alps, his fifth foreign trip as president.
President Trump plans to hobnob with some of the world's wealthiest and most powerful figures at the World Economic Forum at Davos, Switzerland, The White House said Tuesday.
Sanders later told reporters "the main reason he is going there" is to "talk about the America First agenda". An administration official at the time said participating in the high-powered annual meeting would betray the president's populist movement.
US President Donald Trump and India's Prime Minister Narendra Modi could meet - or walk into each other - in Davos, Switzerland later this month. President George Bush, both father, and son, never came to the village in the Swiss mountains, and President Barack Obama also never appeared at the conference.
"Turing away from trade would keep part of our global community forever on the bottom", he said.
The forum will take place from January 23 to January 26. Given its elitist reputation, most presidents have not attended and Trump skipped it previous year; his decision to go may reflect the waning influence of anti-globalists around him, notably fired chief strategist Stephen K. Bannon.
