For Hong Kong leader Carrie Lam the World Economic Forum in Davos is a chance to convince global business and political leaders that the Asian financial hub is back on track. After more than seven months of turmoil Hong Kong’s status as a financial centre has come under scrutiny as sometimes violent demonstrations paralysed parts of the city and forced businesses to close, posing the gravest popular challenge to Chinese President Xi Jinping since he took power in 2012. Lam and “Team HK”, including its trade secretary, top officials from the stock exchange, airport authority, MTR Corp and the head of Swire Group, are in the Swiss mountain resort two days after another violent clash and more are planned for the weekend of her return.
