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 the Czech Republic, the EU Directive was transposed into domestic law through the amendment of the Act on On-Demand Audiovisual Media Services of August 2022 (242/2022 Coll.). According to Section 7 of the Act, on-demand audiovisual media service providers must allocate at least 30% of the total number of programmes in their catalogues to European works and ensure these works are prominently featured. Notably, news programmes, sports events, and competition programmes are excluded from the total number of programmes used to calculate the share of European works.

The Consumer Rights Directive 2011/83/EU provides an updated framework aimed at encouraging online sales. The Directive has been implemented through an amendment of the Consumer Protection Act.

Under the EU Directive on Data Retention, operators were required to retain certain categories of traffic and location data (excluding the content of those communications) for a period between six months and two years and to make them available, on request, to law enforcement authorities for the purposes of investigating, detecting and prosecuting serious crime and terrorism. On 8 April 2014, the Court of Justice of the European Union declared the Directive invalid. However, not all national laws that implemented the Directive have been overturned.
In the Czech Republic, Sections 97.3 and 97.4 of the Electronic Communications Acts provide data retention requirements. It requires electronic communications services to keep 'data packets' (including information on each telephone connection, text message, internet connection or email correspondence) of all clients for a period of six months.
The Constitutional Court of the Czech Republic, in March 2011, judged Sections 97.3 and 97.4 of the Electronic Communications Act to be unconstitutional. However, the data retention regime has remained in place in spite of the Constitutional Court’s reservation. Moreover, in its judgment of 2019, the Constitutional Court concluded that, in fact, a period of six months is not a manifestly disproportionate period and validated the Czech legislation.

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.
The Act on Some Services of Information implements the e-Commerce Directive into Czech law incorporating mere conduit (§ 3), caching (§ 4) and hosting safe harbours (§ 5), and prohibition of general monitoring obligation (§ 6).

Art. 85 of the Utilities Directive (2014/25/EU) contains provisions allowing contracting public entities to reject foreign goods not covered by any EU international commitments from its tender procedures. In these cases, a tender submitted for the award of a supply contract may be rejected where the proportion of the products originating in third countries exceeds 50% of the total value of the products constituting the tender (Art. 85.2). Additionally, in cases of equivalent offers, the provisions provide for a preference for European tenders and tenders covered by EU's international obligations. In practice, this possibility has rarely been used.
In the Czech Republic, the Directive has been transposed with Act No. 134/2016 on Public Procurement.

It is reported that transparency issues pose significant challenges for public procurement procedures in the Czech Republic, particularly affecting foreign bidders. Concerns include overly narrow tender definitions and implicit biases favouring local vendors and state-owned enterprises. Despite government assertions of commitment to transparency, allegations of corruption persist, with media frequently covering failed tenders. Foreign firms have flagged instances of perceived corruption, leading to overturned decisions due to concerns about fairness. Additionally, slow government decision-making often results in delayed or cancelled tenders, with limited political will for re-issuance

The Foreign Investment Screening Act targets foreign investors whose ultimate beneficial owner is from non-EU countries and who acquire at least 10% of voting rights or substantial control over a Czech company in a sector vital to the security, public, or internal order of the Czech Republic (Art. 5). According to Art. 8, foreign investments in sectors involving selected dual-use goods or critical infrastructure, including critical information infrastructure, that could endanger national security or public order, require mandatory authorisation from the Ministry of Industry and Trade (MOIT) before the investment is completed. The screening process lasts 90 days, and if a national security risk is identified, the Czech government has an additional 45 days to decide whether to approve, conditionally approve, or prohibit the transaction (Art. 13).
