Lau Siu-kai, vice-president of the Chinese Association of Hong Kong and Macao Studies, said the vitality of the "one country, two systems" lies in its forward-looking and self-correcting mechanism. Under the principle, the central government exercises overall jurisdiction over Hong Kong and Hong Kong enjoys a high degree of autonomy. That makes it possible for Hong Kong to return to the right track without a complete overhaul of the institutional setting, he added, citing the positive outcomes that the National Security Law for Hong Kong and the electoral reform have brought to the city.

Brave Chan Yung, a Hong Kong deputy to the National People's Congress, said the nation's prosperity serves as the strongest backing for the implementation of "one country, two systems". With the central government's full support, Hong Kong has the greatest confidence to give full play to its strengths, he said.
