US President Donald Trump has been expected to grab world attention with his message on the America First policy and the opportunities for European and international partners.

This will be the first visit of a US leader to Davos over the past 18 years.

Last time, the summit in the Alpine resort was attended by Bill Clinton in 2000.

The Davos forum hosts 1,900 business leaders and also more than 200 media executives, 50 prominent culture figures and over 30 "technology pioneers."
