In the wake of cross-border securities firms like Futu, Tiger Brokers, Long Bridge, and Huasheng Securities, certain Chinese-backed securities firms operating in Hong Kong have also embarked on a restructuring of their existing mainland businesses. On September 28, reports surfaced indicating that, in adherence to regulatory mandates, Guotai Junan International has instituted partial modifications to the services accessible to investor accounts from mainland China, effective from the 26th of the current month. As per statements from their customer service representatives, these adjustments mirror those implemented by securities firms such as Futu Holdings and Tiger Brokers: When existing investor accounts from mainland China log in from within mainland China (as denoted by the login IP), they will be barred from making deposits and purchases, with withdrawals and sales being the only permissible actions. Conversely, if the account login IP signifies a location outside of China, the deposit, withdrawal, and trading functionalities remain unimpeded. Should a client acquire a new identity and subsequently update their identification details, thereby becoming an overseas identification holder, they will be exempt from this restriction.
