On December 29, 2017, the China Securities Regulatory Commission announced the launch of a "full circulation" pilot for listed companies of H-share. "Pilot projects" will adhere to the principle of active, steady and gradual progress, and will be carried out in an orderly manner for any enterprise with mature conditions one-after-another. The first batch enterprises of the pilot project will not exceed three.

In January 2018, the pilot business of "full circulation" of H shares was officially launched. SSCC, together with Shenzhen Stock Exchange, Hong Kong Stock Exchange, China Securities Depository and Clearing Corporation Limited Shenzhen Branch and domestic and overseas securities dealers, provides "full circulation" services for H shares. The pilot work of the full circulation of H shares was based on the existing B-to-H technology platform, with Shenzhen Securities Company responsible for technical services and China Securities Depository and Clearing Corporation Limited Shenzhen Branch as the nominal holder. Domestic securities companies can make transactions and non-transactions declaration through the H-share full-circulation platform, and the processing results of overseas securities companies can also be sent through the H-share full-circulation interface.

H-share full circulation refers to the circulation process of the domestic shares of H-share companies converting into H shares for trading. H shares are shares approved by the CSRC, registered in the mainland and listed on the Hong Kong market for subscription and trading by overseas investors. Under the framework of mainland enterprises going to Hong Kong for listing, the shares held by domestic shareholders before listing are "domestic shares" and those held by foreign investors are called "foreign shares" and domestic shares cannot be circulated in overseas markets. Under such a framework, the shares can only be transferred between mainland legal persons or natural persons, eligible foreign institutional investors or strategic investors, and are in a non-tradable state compared with that in the open market.The Hong Kong Securities Regulatory Commission and the Hong Kong Stock Exchange pointed out that the full circulation of H shares will not only help increase the circulation of issued shares, but also help attract mainland issuers to list in Hong Kong, and the pilot will actively promote the development of the Hong Kong market. From the perspective of corporate governance, the full circulation of H shares will ensure that the interests of major shareholders and public shareholders are consistent.
