Financial Secretary Paul Chan has arrived in San Francisco to promote opportunities brought by the Greater Bay Area to major business communities, as well as industrial and tech enterprises.

As well as a luncheon and a "Bay-to-Bay Dialogue", Chan will also attend the "US-China High-Level Event on Subnational Climate Action", to seek environmental collaboration between the two countries.

The Hong Kong delegation includes representatives from over 10 government departments and organisations.

They include Commerce Secretary Algernon Yau, Transport Secretary Lam Sai-hung, Under Secretary for Financial Services and the Treasury Joseph Chan, and members from InvestHK, the Monetary Authority, Hong Kong Exchanges and Clearing and the Hong Kong Science and Technology Parks Corporation.

Chan is also expected to hold meetings with startups, as well as financial and green tech companies.

His arrival in the US follows a five-day trip to France where he visited the "VivaTech" conference along with more than 10 SAR firms displaying their latest technological innovations.
