China's Xi: HK formula of governance to stay

STORY: "For such a good system, there is no reason to change it at all. It must be maintained over the long term," Xi said. "After experiencing ups and downs, everyone can painfully feel that Hong Kong cannot be chaotic, and must not become chaotic again… we must eliminate all interference and concentrate on development."

Lee, a former police officer, further emphasised the rule of law as being fundamental to the financial hub's success in his speech.

At the swearing-in ceremonies, all officials, including Xi, wore masks and did not shake hands.

Lee, sanctioned by Washington over his role in implementing the security law, takes charge as the city is facing an exodus of people and talent amid some of the toughest COVID-19 restrictions in the world.
