As a major international financial centre, Hong Kong has a prudent and robust financial regulatory regime. Hong Kong's economy has always been closely connected to the Mainland's development. As the Mainland becomes the world's second-largest economy, Hong Kong has given full play to its considerable advantages by contributing to national development. Hong Kong has served as a bidirectional gateway connecting the Mainland and international markets. As of June 2023, more than 1400 Mainland enterprises are listed in Hong Kong with a combined market value of over US$3 trillion, or over 70 per cent of the total market capitalisation in Hong Kong.
