China's top legislator Zhang Dejiang said Sunday the central authority will act strictly in compliance with the Constitution and the respective Basic Law of Hong Kong and Macao.

Zhang, chairman of the National People's Congress (NPC) Standing Committee, made the remarks when joining group deliberations with national lawmakers from Hong Kong and Macao, two special administrative regions.

Hong Kong and Macao will experience an important period in the next five years with significant opportunities for development, Zhang said, adding that the central authority will continue to adhere to the principles of "one country, two systems," the people of Hong Kong governing Hong Kong, the people of Macao governing Macao, and both regions enjoying a high degree of autonomy.

Hong Kong and Macao should continue in the right development direction, consolidate consensus for development, display their unique advantages and functions, and promote the "one country, two systems" practise along the correct path, the top legislator said.

"Hong Kong's biggest advantage is its reliance on the inland areas of the motherland," Zhang told the national lawmakers from Hong Kong, urging the region to "seek development, maintain stability and promote harmony", and seize opportunities in the country's implementation of the 13th Five-Year Plan and the Belt and Road Initiative.

When meeting with lawmakers from Macao, Zhang urged the region to take advantage of the country's 13th Five-Year Plan and the central authority's supportive policies to Macao, and bolster a moderately diversified economy.
