Financial Secretary Paul Chan on Sunday said Hong Kong would seize the momentum of joint developments in the fields of finance and innovation and technology to promote high quality economic development.

Writing on his blog, Chan said Hong Kong welcomed the first mainland firm specialising in making graphics processing units onto its bourse in the New Year, adding the firm was among the country's best in the field.

"In the past two plus years, this firm has collaborated with local artificial intelligence and scientific research organisations in Hong Kong for new solutions," he wrote on his blog.

Chan noted the firm has partnered with Cyberport to set up the hub's first AI lab, while looking proactively into using the AI Supercomputing Centre there to build up the city's computing infrastructure.

The minister said this was one of many examples of the SAR linking up with mainland tech firms — with the Hong Kong-Shenzhen Innovation and Technology Park in Hetao another prime example.

He noted the majority of office space in its first batch of completed buildings there is being filled by some 60 firms from around the world.

Half of them are related to AI and data science, Chan said, and another 40 percent focusing on life and health sciences.
