【明報專訊】IN his first government work report, Premier Li Keqiang, when talking about Hong Kong and Macao, said the "one country, two systems" principle must be upheld, but made no mention of "Hong Kong people governing Hong Kong" and "a high degree of autonomy". This has sparked widespread discussion and speculation. There are those who say the central government has not changed its Hong Kong policy, and there are those who believe the central government is placing less emphasis on Hong Kong's high degree of autonomy, and may tighten its control over Hong Kong.
