Hong Kong leader Carrie Lam on Tuesday ruled out further concessions to the city’s pro-democracy movement ahead of her weekend visit to Beijing, despite a landslide election defeat for the government and a peaceful mass march. The movement, which marked its six month anniversary on Monday, was initially sparked by a now-abandoned attempt to allow extraditions to mainland China but has since morphed into a popular revolt against Beijing’s rule. In a rare lull in police-protestor clashes, around 800,000 people marched peacefully through the city’s streets Sunday, urging the government to respond to their five demands — which include an independent inquiry into the police, an amnesty for those arrested, and fully free elections.
