In a hotel lobby on Hong Kong Island, a delivery robot pauses outside one of the lifts as the doors open, and a guest steps out. The robot waits, and then rolls neatly inside. The move looks simple, but it isn't. To work in the busy hotel, owned by an international chain, the robot must navigate a building that won't slow down for it. People are often getting in the way, and it must be able to take the lift to the correct floor, and then find the right room.

The company behind the robot, Yunji, is a mainland Chinese tech business that is aiming to use Hong Kong as a springboard for successful overseas expansion. We aim to make our product succeed in Hong Kong, and then expand outward, says the firm's vice-president, Xie Yunpeng.

Hong Kong is becoming increasingly important to such mainland Chinese tech companies as a place to raise money, test products with international clients, and build credibility for overseas expansion. This matters because US and European nations have grown more wary of such Chinese companies. Dubbed 'China risk' by some commentators, countries fear state-led espionage and excessive Chinese domination of their tech sectors.

As a result, mainland Chinese firms are finding access to capital, customers, and trust harder to secure in some international markets. Thus, they are looking to Hong Kong in the first instance. According to a report by PricewaterhouseCoopers, the number of mainland Chinese firms listing on the Hong Kong Stock Exchange increased from 30 in 2024 to 76 last year, marking a remarkable growth of 153%.

Invest Hong Kong, the investment promotion agency for the special administrative region, has also reported a rise in the number of mainland firms it has helped to set up or expand in the territory, particularly in the innovation and technology sectors.

Xiaomeng Lu, a director at political consultancy Eurasia Group, states that mainland Chinese tech firms are shifting to Hong Kong for their primary share listing as geopolitical headwinds dampen their dreams to float in New York. Additionally, Wendy Chang of the Mercator Institute for China Studies notes that Hong Kong is fashioning itself as a connector for international business, facilitating the processes for mainland firms aiming for overseas operations.

However, even with a Hong Kong base, these companies still face stringent regulations and scrutiny from international markets, particularly the U.S. and Europe, which have tightened security reviews of Chinese investments due to concerns over data access and critical infrastructure.

In the long run, the strategic value of Hong Kong continues to rise for high-tech Chinese companies, as it presents an opportunity to meet international standards while assuring global investors of their compliance and reliability.
