Financial Secretary Paul Chan has called on countries to promote collaboration among public, private and philanthropic sectors so as to encourage private investments in green and transition projects.

At the World Economic Forum (WEF) Annual Meeting in Davos, Switzerland, on Tuesday, he joined a breakfast meeting organised by the Giving to Amplify Earth Action launched by the WEF.

He pointed out that there was a significant funding gap globally in responding to climate change and highlighted Hong Kong's role as a leading green finance hub in Asia, gathering financial institutions, professional services and talent with relevant expertise.

Chan said the thriving ecosystem of family offices, private equity funds, wealth and asset management was conducive to connecting wealth with climate transition projects.

He briefed attendees at a luncheon meeting on Hong Kong's latest economic situation and development strategies, highlighting its collaboration with sister cities in the Greater Bay Area.

Chan met the Director-General of the World Intellectual Property Organization (WIPO), Daren Tang, to exchange views on strengthening cooperation in areas such as intellectual property protection and talent training.

The financial secretary also met the United Arab Emirates' foreign trade minister, Thani bin Ahmed Al Zeyoudi, to discuss bilateral cooperation in finance and trade.

During his attendance at Davos, Chan has highlighted Hong Kong's unique advantages, such as its role as a "super connector" and "super value-adder" between mainland China and the world, saying this creates opportunities for global businesses and investors.
