Chief Executive John Lee said on Sunday that Hong Kong should continue to improve its economy and people's livelihoods with its special advantages of strong national support and close links with the world under "One Country, Two Systems".

Speaking at the National Day reception, he said the world is changing rapidly, but China continues to strive for excellence despite the complex environment.

He noted that China's economy has been growing faster than the world average, and it is the world's leading country in terms of manufacturing, trade and foreign exchange reserves, as well as the world's second largest consumer market and the world's second largest economy.

He said China's high-quality development on all fronts has brought endless opportunities to Hong Kong.

The CE said the SAR must seize the opportunity to increase its competitiveness, adding that the government is making every effort to promote economic development, including a large-scale campaign to promote night-time economic activities.

"Hong Kong people have weathered the storms and passed the tests. Hong Kong people are smart and know how to work flexibly to turn crises into opportunities. Each time, Hong Kong has become more successful," he said.

"Let us unite and work hard to build a strong and modern country, realise the great rejuvenation of the Chinese nation and ensure the long-term prosperity and stability of the SAR."

He noted that over the past two months, he and his team have held more than 40 consultations and reached out to the community to gather views for his policy address to be delivered later this month.

He said he would take into account various views and introduce policies that would improve people's livelihoods and the city's economy.
