In order to further deepen the mechanism of stock market interconnection between the mainland and Hong Kong and promote the common development of the capital markets of the two places, the China Securities Regulatory Commission and the Hong Kong Securities and Futures Commission agreed in principle that the exchanges of the two places should include qualified exchange-traded funds (exchange-traded funds) in interconnection. Based on the principles of fund size, tracking index stock selection and interconnection of underlying stocks, the two places will determine qualified mainland ETF and Hong Kong ETF to be included in the target scope. Detailed terms and conditions will be issued by the two exchanges. Investors who invest in ETF through interconnection can only trade in the secondary market and are not allowed to apply for purchase and redemption. From the date of this joint announcement to the formal implementation of the above plan, it will take about 2 months to prepare, and the formal implementation time will be announced separately.
