Prime Minister Narendra Modi will address the opening plenary at the WEF's Davos summit next week, while the keynote address will be given by US President Donald Trump at the annual jamboree of the global elite to be attended by 70 state heads.

Swiss authorities on Thursday warned about unauthorised and potentially violent protests targeting this year's World Economic Forum in Davos and its star attraction, US President Donald Trump.

US President Donald Trump will attend the World Economic Forum in Davos later this month, opening up a distinct possibility of a meeting with Prime Minister Narendra Modi.
