Hong Kong can serve as a gateway for mainland firms seeking overseas expansion, Financial Secretary Chan Mo-po said in a blog on June 28. Under Beijing’s “dual circulation” strategy, Hong Kong’s international platform can help mainland companies link R&D to global markets and convert tech innovation into overseas orders. Chan said the city can attract international long-term capital for hard‑tech companies that require patient capital, supporting a “small, early, long‑term” investment approach to scale promising technology and emerging industries.
