Hong Kong is a dependable link that connects the world with opportunities emerging from China's growth and certainty, Chief Executive John Lee said on Tuesday, with the country and the SAR having much to offer amid an ever-changing external environment.

In a keynote speech at the South China Morning Post's China Conference, Lee warned that international trade uncertainties and chaos were likely to persist amid growing protectionism and unilateralism.

But he said that the mainland's expanding trade and capital flows "helped buoy the economy" in the region and the world "in spite of a damaged global trade order".

"In this era of fogged horizons, China does not just project power, it radiates investible stability," Lee said.

He pointed to the country's 5.4 percent GDP growth in the first quarter of this year, saying it was "well on its way" to meeting the official annual growth target of around 5 percent.

Lee forecast Hong Kong would see its economy grow by 2 to 3 percent this year, following a year-on-year 3.1 percent rise in the first quarter.

Lee made reference to the recent five-day maiden visit by the nation's first domestically built aircraft carrier, the Shandong, saying its fleet was "more than a display of maritime strength" and showcased the country's commitment to peacekeeping and regional stability.

"Much like how the Shandong docked in our safe harbour, Hong Kong is where the country anchors its trust," Lee said.

He went on to highlight the SAR's role in acting as a vital link for the world to rely on in the current geopolitical situation.

"Hong Kong is the 'super connector' and 'super value-adder' that links the world with opportunities from China's growth and certainties. A link you can always bank on," he said.

"Amid an ever-changing geopolitical landscape and constantly escalating uncertainties, Hong Kong is the place that promises security and development. This certainty of security and development is precisely what a world of investors needs and thirsts for."
