Cambodia has appended the World Trade Organization (WTO) Telecom Reference Paper to its schedule of commitments.

It is reported that the Telecommunication Regulator of Cambodia (TRC), the executive authority for the supervision and administration of services in the telecommunications sector, is independent from the government in the decision-making process.

Pursuant to Art. 109 of the Law on Commercial Enterprises, a company is required to prepare and maintain at its registered office in the Kingdom of Cambodia the following corporate records: the articles of incorporation and by-laws, together with any amendments thereto; minutes of meetings and resolutions of shareholders; copies of all notices mandated by law to be issued or filed; and a register of securities. In addition, in accordance with Art. 113, a company must also prepare and retain adequate accounting records for a minimum period of ten years following the conclusion of the financial year to which such records pertain. In instances where these accounting records are maintained outside Cambodia, duplicate copies must be preserved at the company’s registered office within the country.

Art. 51 of the Law on Customs stipulates that all individuals or entities engaged in the import or export of goods must maintain accurate documentation, including books, records, and other information, in both digital and traditional formats. These records must be retained for a minimum of 10 years at the business premises in Cambodia. This obligation extends to importers, exporters, customs brokers, operators of customs temporary storage facilities and customs bonded warehouses, transportation operators, and other relevant parties.

Art. 6 of Sub-Decree No. 287 stipulates that ministries and governmental institutions intending to utilise the national domain name designated for such entities must store their data within the Kingdom of Cambodia. The Ministry of Post and Telecommunications is responsible for hosting and storing the data of all ministries and governmental institutions using national domain names, either in the national data centre or in a government-operated data centre.

Cambodia is a party to the Patent Cooperation Treaty (PCT).

Cambodia is not a signatory of the 1996 World Trade Organization (WTO) Information Technology Agreement (ITA) nor the 2015 expansion (ITA II).

In accordance with Art. 12 of the Law on Public Procurement, international competitive bidding is applied to procurement activities of substantial value and high technical complexity. Conversely, domestic competitive bidding is used when sufficient domestic products, production capacity, or construction capabilities are available. This 2023 legislation replaces the previous Law of the same name enacted in January 2012, which included a similar provision under Art. 11.
According to Art. 11 of the 2023 Law, the conditions, thresholds, and procedures for implementing each procurement method shall be determined by a Prakas issued by the Minister of Economy and Finance. Although the relevant implementing regulation could not be found online, it is reported that in November 2023, Cambodia amended the thresholds for international competitive bidding through Prakas No. 833, setting them at (i) KHR 10 billion (approx. USD 2.5 million) for goods and (ii) KHR 8 billion (approx. USD 2 million) for services.
Additionally, pursuant to Chapter 6 (Qualifications of Bidders) of the Law on Public Procurement, the Ministry of Economy and Finance (MEF) requires all companies, contractors, and consultants wishing to participate in public procurement tenders to register with the MEF and undergo a screening process.

Government procurement in Cambodia is reported to lack transparency, with tenders often announced with short response times and published only on the Ministry of Economy and Finance (MEF) website. Irregularities in the procurement process are common, despite legal requirements for audits and inspections. Although there have been allegations of misconduct in several ministries, the government has taken little action to investigate. It is reported that while the 2023 Law on Public Procurement introduced additional provisions aimed at strengthening the regulation and management of public procurement, stakeholders have not observed any significant improvements in practice.

It is reported that the government has included domestic preferences for SMEs in public procurement procedures; however, this practice is not specified in legislation.

Cambodia is not a party to the World Trade Organization (WTO) Agreement on Government Procurement (GPA) nor does it have observer status.

According to Art. 3 of the Law on Public Enterprises, the Cambodian government must directly or indirectly hold more than 51% of the capital or voting rights in state-owned enterprises. As Telecom Cambodia—the country's principal telecom company—is fully state-owned, certain restrictions apply to this entity.

Under Arts. 10–12 of Cambodia’s Law on Investment, any person seeking to implement a Qualified Investment Project (QIP), Expanded Qualified Investment Project (EQIP), or Guaranteed Investment Project (GIP) must submit a written Investment Project Application to the Council for the Development of Cambodia (CDC). The CDC assesses the application through its One-Stop Service mechanism, which operates through seconded representatives of relevant ministries and institutions acting under delegated decision-making authority. Where the proposed investment is not included in the Negative List (to be specified by Sub-Decree), the CDC must issue a Registration Certificate within 20 working days.
In addition, Art. 11 of Sub-Decree No. 60 (2016) requires the CDC to refer specified categories of projects to the Council of Ministers for approval, including projects with investment capital of USD 50 million or more, projects involving politically sensitive issues, projects relating to the exploration or exploitation of mineral and natural resources, projects that may have negative environmental impacts, projects characterised as long-term strategic, and projects involving infrastructure concessions.
