Chief Executive John Lee on Tuesday welcomed confirmation by the Asian Infrastructure Investment Bank (AIIB) that it will set up an office in Hong Kong, saying the city's financial markets are shining despite an uncertain global outlook.

He made the remarks as he delivered a keynote speech at the Global Financial Leaders' Investment Summit at the Rosewood Hotel in Tsim Sha Tsui.

"As a committed member of the AIIB, Hong Kong will do all we can to support its establishment of an office here. That includes leveraging our vibrant capital markets, world-class professional services and diversified products," Lee told some 300 global financial heads.

"We will also help the AIIB in project financing, bond issuance, investment management and much more."

AIIB's office in Hong Kong will be its second outside the mainland, with the other in Abu Dhabi. It is expected to begin operations next year.

Separately, Lee said Hong Kong is now shining on the global stage, with the local stock market up over 30 percent year to date, with an average daily turnover almost double from a year ago exceeding US$32 billion.

The city's fundraising market, meanwhile, is also leading in the world, with 80 initial public offerings raising a total of over US$26 billion in the first 10 months of the year, he added.

"I still remember that when I addressed the inaugural summit in 2022, a time when the world was emerging from the Covid-19 pandemic, I said the event showed that Hong Kong was onstage again," he recalled.

"Three years on, I'm proud to say that Hong Kong now shines on the global stage, radiating prosperity, confidence and much-needed reassurance."

All of this, he said, is thanks to the "One Country, Two Systems" principle that has enabled the city to reach out to global markets while maintaining "unparalleled" access to the mainland.

Lee called on global investors who are seeking to diversify their assets to come to the city, saying the SAR offers certainty amid geopolitical changes and market volatility.
