Zhao stated that Beijing seeks cooperation and dialogue with Washington but will fight back if the United States tries to oppress China, RIA Novosti reported.
The day before, the South China Morning Post newspaper reported, citing sources that Beijing was set to put forward a resolution that will allow the National People's Congress during its upcoming session to pass national security legislation to ban secession and foreign interference in Hong Kong.
Hong Kong has been gripped by violent protests since June. Numerous demonstrators initially took to the streets to protest a proposed extradition bill, but riots continued and became violent even after the unpopular measure was withdrawn in October.
Beijing has announced that the situation in Hong Kong was the result of foreign interference in China's domestic affairs and expressed full support for the local authorities to avert violence and restore order.
