According to Art. 25 of the Chinese government’s 2015 National Security Law, all information systems in China must be "secure and controllable". As a result of this policy, it is reported that every company operating in China – whether domestic or foreign – is required to provide the Chinese government with access to its source code, encryption keys, and backdoor access to their computer networks in China.

The Anti-Unfair Competition Law of the People's Republic of China, which was implemented by the Several Provisions on Prohibition of Infringement of Trade Secrets Act, provides a framework for the effective protection of trade secrets. According to Art. 2 of both laws, the term "trade secrets" refers to technical information and business information that is not known to the public, can bring economic benefits to the right holder, is practical, and has been kept confidential by the right holder. Art. 3 of the Several Provisions on Prohibition of Infringement of Trade Secrets Act outlines prohibitions against trade secret infringements, including obtaining trade secrets through improper means such as theft or coercion and disclosing or using such secrets. It also covers violations by business partners and employees who breach confidentiality agreements, as well as third parties who knowingly use or disclose obtained trade secrets. Moreover, Art. 7 states that violations of Art. 3 will be addressed by the administration for industry and commerce according to Art. 25 of the "Anti-Unfair Competition Law," which may involve ordering the cessation of illegal activities and imposing fines ranging from 10,000 to 200,000 yuan (approx. USD 1,500 to USD 30,000).

Particularly troubling are reports that agents affiliated with the Chinese government and military have infiltrated the computer systems of foreign companies, stealing terabytes of data, including proprietary information and intellectual property, to provide commercial advantages to Chinese enterprises.

Art. 10 of the Government Procurement Law states that procuring entities must procure domestic goods, construction, and other services, except in one of the following situations: (i) where the goods, construction, or other services needed are not available within the territory of China or cannot be acquired on reasonable commercial terms, even if they are available in China; (ii) where the items to be procured are for use abroad; and (iii) where otherwise provided for by other laws and administrative regulations.
Moreover, the Chinese public procurement regulations actively promote a Buy Chinese policy. In principle, only Chinese companies are allowed to bid in public tenders, with foreign companies permitted only under exceptions. Government agencies and related entities are required to purchase equipment and technology from Chinese state-owned or privately-owned manufacturing companies. It is reported that public tenders often lack sufficient publicity. Furthermore, central and local entities tend to implement these provisions very broadly, exceeding the discriminations imposed by the law.

A report by the National Development and Reform Commission of China and the Ministry of Finance bans the purchase of certain foreign IT products for selected government procurement lists.

Products from Dell Inc., Hewlett-Packard Co. and Chinese maker Lenovo Group Ltd. were included on both lists. This ban applies to all central Communist Party departments, government ministries and local governments.
