HONG KONG - The Hong Kong Exchanges and Clearing Limited (HKEX) said on Monday that it will continue to improve connectivity schemes between the capital markets of the Chinese mainland and the Hong Kong Special Administrative Region, including the Shanghai-Hong Kong and Shenzhen-Hong Kong stock connects, the Bond Connect program and Swap Connect.

Since the Shanghai-Hong Kong Stock Connect, the first connectivity scheme, launched on Nov 17, 2014, the schemes have provided domestic and foreign investors with convenient and efficient cross-border asset allocation channels and injected liquidity into the capital markets of the Chinese mainland and Hong Kong, said the HKEX in a white paper.
