The Swiss Alpine town of Davos is used to celebrities and high-rollers, but even it is relishing new attention being heaped on it with U.S. President Donald Trump's decision to attend the World Economic Forum this month.

Trump's visit to Davos for the annual meet-up of global political and business leaders will be the first for a sitting U.S. president since Bill Clinton came in 2000.

Trump's policies, including his intention to exit the 2015 Paris climate accord and his "America First" tendencies, may not sit well with all of Switzerland, which backs the global climate pact and whose economy relies on global trade.
