China's Plan to Take Charge of 'Serious' National Security Cases in Hong Kong Sparks Concern Verna Yu HONG KONG - China musttake charge of "serious" cases in Hong Kong that breach national security, a senior Chinese official said this weekas Beijing prepares to impose new national security laws in the city. Analysts and legal experts say Hong Kong's freedoms are under unprecedented threats after China's parliament, the National People's Congress, passed a plan in late May to impose sweeping national security laws on Hong Kong to prevent and punish what Beijing considers "acts and activities" that threaten national security, including advocacy of secession, subversion and terrorism and foreign interference. The plan, which bypassed Hong Kong's legislature, would also allow Chinese national security organs to set up agencies in the city. The laws are expected to be enacted within the next few months, with some reports suggesting it could take effect as soon as late June or July. China insists such laws are necessary to halt widespread anti-government protests in Hong Kong, which started off being peaceful in June last year but turned violent as frustrations mounted. .
