Where is Devoas – the venue of the annual meeting of World Economic Forum, located?

The annual meeting of the World Economic Forum is held in Davos (the question’s spelling “Devoas” appears to be a variant/error). Davos is a Swiss Alpine town in the canton of Graubünden and has been the long-standing venue for the WEF Annual Meeting; Swiss authorities and WEF event pages explicitly refer to the meeting taking place in Davos (Davos‑Klosters), Switzerland . Official descriptions of the event and government information about hosting, security and local involvement all identify Davos in Switzerland as the site for the Forum’s annual gathering, so the correct answer is Switzerland.
