Macau on Friday celebrated 20 years since the former Portuguese colony was returned to China with President Xi Jinping praising the pliant gambling hub for its patriotism, a stark contrast to protest-ravaged Hong Kong. Ho Iat-seng, a former member of China’s top lawmaking body, won a one-horse race this summer to become Macau’s new chief executive — a position that is chosen by a 400-member committee stacked with Beijing loyalists. Throughout his three-day visit, Xi has seized on Macau’s comparative political calm, a theme he continued in Friday’s landmark speech as he presided over Ho’s swearing-in ceremony.
