Sudan has a copyright regime under the law Copyright and Neighbouring Rights Protection and Literal and Artistic Works Act, 2013. However, the exceptions do not follow the fair use or fair dealing model, therefore limiting the lawful use of copyrighted work by others. Arts. 26-32 list the exceptions, which include educational purposes, quotations, transfer or copying from newspapers, copying for legal proceedings, news reports, photocopying in libraries and publishing by mass media.

Sudan has not signed the World Intellectual Property Organization (WIPO) Copyright Treaty.

Sudan is not a signatory of the 1996 World Trade Organization (WTO) Information Technology Agreement (ITA) nor the 2015 expansion (ITA II). Sudan is not a member of the WTO but holds observer status.

Chapter 5 of the Purchasing, Contracting and Surplus Disposal Act stipulates that:
- Priority in contracting for the purchase and implementation of works shall be given to Sudanese individuals and institutions licensed to operate according to this Act (Art. 14.14);
- The Ministry may specify some works and contracts whose implementation must be entrusted to Sudanese contractors, and the projects can also be divided to allow Sudanese contractors to qualify and implement them (Art. 14.15); and
- Government agencies are required to prioritise Sudanese industries and products, provided they meet the intended purpose of the purchase (Art. 14.19).

The Purchasing, Contracting, and Surplus Disposal Act has introduced several limitations on foreign participation in public procurement, including:
- Foreign bidders must use local suppliers for specific services and ensure that at least 20% of the project is carried out by Sudanese contractors (Art. 14.16).
- Contractors are also obligated to purchase necessary tools and equipment from Sudanese agents, with direct imports allowed only if items are unavailable locally (Art. 14.17).
- National products may be procured if their prices do not exceed foreign alternatives by more than 10%, with foreign products acceptable only if they meet the required specifications (Art. 14.20).

Sudan is not a party to the World Trade Organization (WTO) Agreement on Government Procurement (GPA), nor does it have observer status. In fact, Sudan is not a member of the WTO.

According to Art. 18 of the Investment (Encouragement) Act, foreign investment is restricted in certain sectors as designated by the Minister. It is reported that such restrictions include a prohibition on foreign capital participation in most areas of telecommunications services.

According to Art. 39.2 of the Companies Act, at least one of the directors on the board of any company must be a resident of Sudan.

Pursuant to Art. 22.1 of the Investment (Encouragement) Act, foreign investors are required to provide a minimum amount of foreign capital. Reports indicate that this amount must be no less than USD 250,000 or its equivalent in foreign currencies approved by the Central Bank of Sudan, as proof of commitment. It is anticipated that forthcoming regulations shall clarify the specific authority to which investors must remit this amount, as the New Investment Act does not currently stipulate this. The capital provided will be allocated to financing the respective project upon the issuance of the relevant license (Art. 22.2).

According to Art. 33 of the Companies Act 2015, companies incorporated outside Sudan that wish to conduct business within the country must establish a branch in Sudan. Additionally, companies engaged in projects in Sudan are required to set up a branch specifically for the duration and purpose of the project (Art. 34).

São Tomé e Príncipe has not adopted national legislation based on the United Nations Commission on International Trade Law (UNCITRAL) Model Law on Electronic Signature.

Self-certification is allowed in São Tomé e Príncipe for radio transmission, electromagnetic interference (EMI) or electromagnetic compatibility (EMC). São Tomé e Príncipe allows foreign companies to self-certify that they comply with these standards through a Supplier Declaration of Conformity (SDoC).

São Tomé e Príncipe does not implement any de minimis threshold, which is the minimum value of goods below which customs do not charge duties. However, it is reported that the country applies informally a de minimis threshold of 29 USD.

São Tomé e Príncipe lacks a comprehensive framework for consumer protection that applies to online transactions.
