HONG KONG - Erick Tsang, Secretary for Constitutional and Mainland Affairs of China's Hong Kong Special Administrative Region (HKSAR) government, said on Sunday that national security legislation for the HKSAR will not harm the rights and interests of Hong Kong residents and it will only target serious acts such as separatism.

Tsang told the media that the HKSAR government will fully cooperate with the central authorities in the legislative work. Both law enforcement agencies of the HKSAR and mainland institutions in the HKSAR are required to abide by laws, including the laws of the HKSAR.

He reiterated that the legislation and law enforcement in the future will not affect the legitimate rights and interests of Hong Kong residents.

Talking about the US threat to impose sanctions on HKSAR officials, Tsang said the legislation is legal and constitutional so he is not worried at all.
