The head of Beijing's liaison office in Hong Kong, Luo Huining, said on Thursday that he believes the commercial and industrial sectors will seize Hong Kong's development opportunities as the SAR faces a key new chapter in the coming five years.

At a seminar on the sectors' involvement in the country's Belt and Road initiatives, he said they have always had sensible market judgement as they comprise of the world's business talent, and he's sure they will integrate into the country's development plans.

"I believe you will all actively grasp Hong Kong's development direction, fortify its international status as financial, aviation and trade hubs, build up its international innovation technology centre, and keep raising the economy's competitiveness," he said.

"I also believe you will actively integrate into the country's development plans in the latest Five Year plan, be comprehensively involved in the construction of the Greater Bay Area and cultivate new growth momentum."

Luo added that he thinks the sectors will actively adapt to global economic development trends and advance globalisation by getting greatly involved in Belt and Road initiatives so as to achieve win-win developments.

He said the national security law has restored social stability in Hong Kong and has also fortified the SAR's top-notch business environment.

Chief Executive John Lee, meanwhile, said he will keep working on enhancing Hong Kong's development momentum.

Speaking at the same function, he said he will keep working on Belt and Road initiatives and live up to the expectations of President Xi Jinping as well as Vice Premier Han Zheng, who oversees Hong Kong affairs.
