High altitude, fresh air and good food were once thought to be the best way to treat tuberculosis. For those who could afford it, long term visits to exclusive sanatoria like that at Davos in Switzerland meant the chance of an extended life, though little prospect of actual recovery. After the development of antibiotics, these sanatoria often became ski resorts and places of idle pleasure. But in 1971, Davos began hosting an annual summit of well meaning philanthropists and politicians, eager to make the world a better place. In January 2016, China’s presence at the summit was very well received, despite being represented by lesser known members of the Politburo. Indeed, so successful was this visit that Xi Jinping himself is reported to be attending in January 2017, the first Chinese president to attend the World Economic Forum (WEF) at Davos.
