The spokesperson for the national political advisory body on Wednesday denounced mob violence in Hong Kong's Mong Kok that erupted during the Lunar New Year holidays last month.

"We firmly oppose illegal and even violent actions taken by a small number of people to mess things up in Hong Kong and sabotage cooperation and exchanges between the mainland and Hong Kong," the spokesperson for the National Committee of Chinese People's Political Consultative Conference (CPPCC), Wang Guoqing, said.

About 300 people rioted in the early hours of Feb 9 in Mong Kok, one of Hong Kong's busiest shopping areas, following official attempts to remove illegal hawkers from the busy commercial neighborhood.

The rioters attacked police officers and journalists, smashed police vehicles and committed arson. Nearly 90 police officers as well as four journalists were injured.

Describing Hong Kong as an "open and diversified society", Wang said it was perfectly normal that people with different backgrounds would hold different views toward economic, political and social issues.

"But it is the common aspiration of all Hong Kong residents and in the fundamental interest of the city to seek development, stability and harmony," he said.

Hong Kong's long-term stability and prosperity is an overarching mission of the "One Country, Two Systems" principle, and an important part of the Chinese Dream, Wang said.

The "One Country, Two Systems" has been globally recognized, he said, and central authorities will steadfastly uphold its adherence to the principle, and ensure the principle's implementation in Hong Kong.

The country’s development blueprint for 2016 to 2020, Wang said at the annual press conference on Wednesday, focuses to promote the importance of Hong Kong and Macao in the country’s economic development and progress to open up.

He assured the central government will continue to support Hong Kong and Macao to fully use their advantages to participant in the country’s developments.

People and governments of the two regions, he said, should make concerted efforts to cement their existing advantages and explore new competitive edges, in order to meet the country’s needs with the region’s unique strengths.

He urged political advisers from Hong Kong and Macao to play their due parts in its implementation.

Though the five-year plan addresses primarily the blueprint of economy and society on the mainland, Wang assured implementation of the plan is a good news for the two SARs.
