According to Art. 33 of the Decision of the Council of Ministers No. 16 of 2019, tender conditions and draft contracts concluded with non-Qatari companies for the provision of services within Qatar (excluding consultancy services) must include a clause requiring such companies to rely on local markets for no less than 30% of the total contract value. This requirement applies without affecting the technical conditions and specifications upon which the contract was awarded. The stipulated percentage encompasses expenditures on raw materials, locally manufactured products, and services provided by local companies in the performance of the contract.

According to Art. 2 of Law No. 6 of 1987, in tenders, national products are granted a 10% price preference over similar foreign products and a 5% price preference over similar products of national origin. In cases where a national product is not available, products of national origin are afforded a 10% price preference over comparable foreign products.
For the purposes of this provision, national products refer to goods produced within the State of Qatar and recognised as national or local products under Qatari law. Products of national origin are defined as goods in which the value added through production in a Gulf Cooperation Council (GCC) member state constitutes at least 40% of the final value upon completion of production, and where at least 51% of the ownership of the producing facility is held by GCC citizens, as certified by a certificate of origin.

Qatar is not a party to the World Trade Organization (WTO) Agreement on Government Procurement (GPA).

According to Art. 2 of Law No. 1 of 2019 on Regulating Non-Qatari Capital Investment in Economic Activity, non-Qatari investors may invest in all economic sectors, with capital ownership of up to 100%, in accordance with the Minister of Commerce and Industry Decision No. 44 of 2020 issuing the Executive Regulations of the Law. Although the legislation specifies certain sectors excluded from foreign participation - such as banking and insurance, commercial agencies, and any other activities determined by a decision of the Council of Ministers - none of these restrictions are directly relevant to digital trade.

Art. 4 of the Decree-Law No. 262/1986 and Art. 40 of the Decree-Law No. 403/1986 establish that, as a general rule, foreign companies that wish to exercise their activity in Portugal for more than one year must establish a "permanent representation" (i.e. registered office, central administration or principal place of business within host country - Portugal - or in a European Union country) in the country and comply with the provisions set forth under Portuguese law in relation to commercial registration.

The EU Directive on Audiovisual Media Services (AVMS) covers traditional broadcasting services as well as audiovisual media services provided on-demand, including via the Internet. Art. 13.1 provides for Member States to secure a minimum 30% share of European works in the catalogues as well as "ensuring prominence" of those works. "Prominence" involves promoting European works by facilitating access to such works using any appropriate means to ensure their prominence. The Directive has been implemented by Member States in different ways, ranging from very extensive and detailed measures to a mere reference to the general obligation to promote European works.
In Portugal, the EU Directive was transposed into domestic law through the amendment of the Television and Audiovisual On-Demand Services Law of November 2020 (Law No. 74/2020). According to Art. 45.2 of the Act, on-demand audiovisual service operators must ensure that European works comprise at least 30% of their catalogues, giving prominence to such works and allocating at least half of that percentage to independently produced European creative works originally in Portuguese and produced within the last five years.
Furthermore, according to Art. 14-A of Law 55/2012, television service operators, on-demand audiovisual service operators, distributors of cinematographic works, and videogram publishers in Portugal are required to allocate a portion of their investment expenditure to the development, production, and promotion of European and Portuguese-language works, as well as independently produced works. This investment obligation is calculated based on their relevant income from various audiovisual services, allowing for flexibility in selecting specific projects. Small operators may be exempt from these requirements based on their revenue and market share.

The Directive 2000/31/EC (E-Commerce Directive) is the legal basis governing the liability of Internet Services Providers (ISPs) in the EU Member States and includes a conditional safe harbour. Not all Member States have transposed the relevant articles consistently, leading to divergent national case law that could cause legal insecurity on an EU level.
In Portugal, the safe harbour is mainly defined in the Information Decree-Law No. 7/2004 as implementing Directive 2000/31/EC, therefore covering activities of mere conduit, intermediary storage and hosting (Arts. 11 to 19 Decree Law No. 7/2004). Portuguese legislation introduces additional particularities and liability exemptions such as, under certain circumstances, intermediary liability for content aggregation providers, mainly hyperlinking and search engine services (Art. 17 Decree Law No. 7/2004).
