US leader will give speech on Friday, but delegates fear nationalistic tone at global summit.
US President Donald Trump has touched down in Davos, Switzerland, for the World Economic Forum,which he will address for the first time.
Despite Davos being a longstanding annual meeting of the rich, famous, and fabulously wealthy, no invitation had been extended for the property magnate and reality TV billionaire before.
He is not the only world leader with people hanging on his every word, as France's President Macron is expected to bring a number of proposals to try out on the world stage.
Among his side meetings he has already spoken to Israel's Benjamin Netanyahu, and indirectly criticised Trump for his changes to US foreign policy regarding the middle east, and Jerusalem in particular in an hour-long speech centring on economic issues on Wednesday that drew a standing ovation.
President Trump is the first US leader to visit Davos since Bill Clinton in 2000, and will speak on Friday.
