Davos comes as Trump faces crucial decisions about his worldwide economic agenda including whether to rework or withdraw the North American Free Trade Agreement, a move that has many world leaders on edge.
The forum will take place from January 23 to January 26.
Also in USA politics, 85-year-old pardoned former Arizona sheriff Joe Arpaio announced he will run for Jeff Flake's senate seat. Former President Bill Clinton attended the forum in 2000, but former Presidents Barack Obama and George W. Bush did not attend the meetings during the time they were in the White House.
Davos was once held up by the Trump campaign as an example of what was wrong with Hillary Clinton's Democratic party.

Administration spokeswoman Sarah Huckabee Sanders said Trump was eager to attend the meeting of world leaders and business execs.
Some 3,000 business people, government officials and other movers and shakers are expected to attend the elite gathering in the Swiss resort. He withdrew the USA from the Trans-Pacific Partnership, a trade agreement between Pacific Rim countries, and pulled out of the Paris climate accord, a commitment to reduce carbon emissions.
The first sitting United States president to appear in the Swiss resort was Bill Clinton in 2000, at the forum's 30th-anniversary session.
In an interview on Monday prior to the announcement, Harvard University professor Ken Rogoff identified Trump as a risk to the economic expansion.
