The Commissioner's Office of the Ministry of Foreign Affairs in Hong Kong on Saturday has strongly condemned the latest US advisory for American businesses operating in the SAR.

The US Departments of State, Agriculture, Commerce, Homeland Security, and Treasury said in a joint release overnight on Friday that firms operating in Hong Kong are facing "increasing risks" that it said stem from national security laws in the SAR.

In response, the Foreign Ministry's office in Hong Kong said in a statement that national security laws have provided a strong safeguard to the region's business environment.

It pointed out that with the registration of non-local firms reaching a record high and savings at bank increasing gradually, investors' confidence towards Hong Kong is being enhanced.

The office also said it is a usual tactic for Washington to suppress the region's developing by badmouthing the SAR.

It said that not only will US tactics fail to intimidate international investors, it will stain its own international reputation.

It urged Washington to abide by the principles of international law and stop interfering in SAR affairs and the nation's internal matters.
