According to Article 6 of "Several Opinions on Strengthening Management of Technical Secrets" promulgated by Ministry of Science and Technology, in accordance with the provisions of relevant laws, enterprises and institutions may sign confidentiality agreement with the scientific and technological personnel, administrative staff, and employees who may be aware of the technical secrets. In general, employees that should sign confidentiality agreement include:

1. Senior R&D staff, technicians and management personnel, who may hold the core technologies of enterprises, or take charge of management work, or control the critical business information. They are the major group for signing confidentiality agreements.

2. Technical support staff and skilled workers in key posts. Although they are not the crucial group, they may also come into contact with the core technologies, which make it necessary for them to sign confidentiality agreements.

3. Market planners and sales staffs, who are the undertakers of business decisions. Since they know about the marketing plans and customer lists, enterprises shall sign confidentiality agreements with them.

4. Accountants, secretarial staff and security personnel, who may know about the commercial secrets because of their posts. If they do not sign confidentiality agreements, they may disclose the secrets intentionally or unintentionally.
