Financial Secretary Paul Chan on Friday said the city's financial system remains robust, despite intensified geopolitical risks causing greater volatility in regional and global markets.

Chan made the remark during a discussion on "stemming financial fragmentation", at the World Economic Forum Annual Meeting in Davos.

He also said Hong Kong "steadfastly" upholds the linked exchange rate system, or the currency peg, and that recent surveys showed global investors were optimistic about the SAR's business outlook.

Chan added that the city has undergone significant transformations in the stock markets, wealth management and digital asset sectors, as he also stressed that China's economy is steadily growing and achieving high-quality development.

Separately, the finance minister continued to promote green finance projects, as well as "impact investments", or funds aimed at generating social or environmental effects.

Chan held talks on trade with some of his global counterparts, including the investment minister of Saudi Arabia, Khalid Al-Falih, and the finance chief of Egypt, Ahmed Kouchouk. Chan invited the ministers to visit the SAR as part of efforts to deepen ties with the Global South.

He also met Jenny Johnson, CEO of investment firm Franklin Templeton, to discuss how to expand the company's business in the SAR.

Chan is due to return to Hong Kong on Saturday.
