Art. 29 outlines the exceptions, including private performances strictly within family circles, performances given free of charge for educational and academic purposes, and reproductions and transformations in one copy for the strictly personal and private use of the individual who makes them.

According to Art. 26.1 of the E-Commerce Law, e-commerce service providers and intermediaries must obtain e-commerce permits or licenses from the Ministry of Commerce (MOC) in addition to the general business registration. According to Art. 26.2, the licensing regime has two categories: (1) an e-commerce permit (for individual persons and sole proprietorships) and (2) an e-commerce license (for legal persons and branches of foreign companies). In August 2020, Cambodia issued Sub-Decree No. 134, an implementing regulation of the E-Commerce Law, clarifying that a license is required for legal persons and branches of foreign companies carrying out the following activities: e-commerce web services, e-commerce platform services, online market services, online auction website services, and other similar services provided through software or smart devices for the promotion of e-commerce (Art. 5.1).

In addition, pursuant to Art. 5.2 of the Sub-Decree, an E-Commerce permit is required for natural persons and sole proprietors that operate a business via electronic system in Cambodia (including those who conduct business via social media and electronic systems to supply or sell/purchase goods and services). Furthermore, according to Art. 7.1, legal entities or foreign branches that are intermediaries of electronic-commerce service providers must apply for a license at the MOC and meet the following conditions: (i) business registration and tax registration with registered business activities relating to e-commerce; (ii) it must have obtained an Online Service Certificate and domain name from the Ministry of Posts and Telecommunications; (iii) it must use an electronic application or means for operating e-commerce; (iv) the electronic system used by it must be accurate; (v) it must specify the payment method; (vi) it must have a business model and consumer protection form. If it is a legal entity or foreign branch acting as an intermediary, it must enter into a contract with the business service providers. Moreover, in October 2020, the MOC issued the Prakas No. 290 regulation, which set the required documents to apply for e-commerce licenses and permits and detailed procedures and time frames for the MOC to review the applications. The regulation also stipulates the timelines and procedures to renew the permits and licenses, among other things (Arts. 3–8.).

The E-Commerce Law broadly defines e-commerce service providers and intermediaries (Annex). An e-commerce service provider is defined as a "person who uses electronic means to supply goods and/or services except for insurance establishments". On the other hand, intermediary "refers to a person who provides the services of sending, receiving, transmitting or storing services of the electronic communication, either on a temporary or permanent basis, or provides other services relating to the electronic communication, including the following persons: a person representing the sender, receiver, transmitter, or the custodian; telecommunication service providers; network service providers; internet service providers; search engines providers; online payment service providers; online auction service providers; online marketplaces service providers and internet commerce service provider".

Art. 5 of the Law on Foreign Exchange states that foreign exchange operations shall be undertaken solely through authorised intermediaries. These operations include purchases and sales of foreign exchange on the foreign exchange market, transfers, all kinds of international settlements, and capital flows in foreign or domestic currency between Cambodia and the rest of the world or between residents and non-residents. As a result, only banks permanently established in the Kingdom of Cambodia are considered authorised intermediaries for international settlements.
