The Private Investment Law No. 10/21 established the Angolan Investment Promotion Agency (AIPEX) as the primary entity responsible for promoting and regulating private investment. AIPEX serves as a one-stop shop for investment approvals. According to Art. 45, private investors have the responsibility to hire local workers, providing them with adequate training and ensuring working conditions and salaries commensurate with their skills. Although they have the option of employing qualified foreign workers, they must implement a rigorous training plan for national technicians, with the purpose of eventually replacing them with Angolan workers. These training plans and the gradual process of replacing foreign labour should be an integral part of the documentation submitted for any investment proposal. The Regulations for the Private Investment Law No. 250/18 outline the steps for registering and approving private investment projects, with AIPEX overseeing the process. Art. 6 specifies the investment project documentation, including a plan for gradually replacing foreign labour with national labour and the procedures required for registration.

Art. 5 of Law No. 3/92 states that patent applications must be written in the Portuguese language and that foreign applicants must appoint a legal local representative.
