Since May 2020, Hungary has applied an “Alternative FDI Regime”, established under Chapter 85 of Act LVIII of 2020 and its implementing Government Decree. Originally designed as a temporary measure set to expire at the end of 2021, the regime was extended and reinstated through Government Decree No. 561/2022, thereby making it permanent.
The regime applies to a broad range of transactions, not limited to share acquisitions. It encompasses convertible instruments, usufruct rights, corporate transformations, asset purchases, capital injections, and in-kind contributions.
Under Art. 3 of Decree No. 561/2022, notification is required whenever a foreign investor directly or indirectly acquires:
(i) at least a 5% stake in a strategic company (or 3% if the company is publicly listed), provided the transaction value reaches HUF 350 million (approx. EUR 900,000); or
(ii) at least a 10% stake, regardless of deal value; or
(iii) a stake resulting in the combined shareholding of foreign investors reaching 25% in a strategic company, regardless of deal value.
According to Art. 2 of the Decree a strategic company is defined as a limited liability company, a privately held joint-stock company, a publicly held joint-stock company, or a higher education institution with a registered office in Hungary, whose main or additional activity falls within a sector of strategic significance as defined in Annex 1, particularly in the energy, transportation, or communication sectors, as well as industries defined under Regulation (EU) 2019/452 of the European Parliament and Council of 19 March 2019, which establishes a framework for the screening of foreign direct investments into the Union.
Annex 1 lists an extensive coverage of sectors, including publishing activities, telecommunications, and information technology services, among others.

Under Art. 51 of Act XXXIII of 1995 on the protection of inventions, foreign applicants that have no residency within the EU or the European Economic Area (EEA) have to be represented by an authorised attorney-at-law in front of the Hungarian Intellectual Property Office.

Under Art. 62. k of the Act CLXLIII on Public Procurement, foreign firms are excluded from government procurement if they are registered in a country that is neither an EU member nor a member of the WTO Government Procurement Agreement nor if they are registered in a country that has no double taxation treaty with Hungary or the EU.

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 Hungary, the Directive has been transposed with Act CXLIII of 2015 on Public Procurement.

Art. 106 of Law No. 5/2010 provides that the Autoridade Reguladora Nacional (ARN, National Regulatory Authority) is responsible for determining the approval of equipment used in the provision of information and communications services to interconnect or operate telecommunications systems and terminal equipment. The ARN's approval determinations may be conferred under the terms of this Law No. 5/2010 or in certificates granted by the ARN or by competent organisations authorised by the ARN. Terminal equipment intended to be connected to a network open to the public must be approved by the ARN. In any case, approval is always required in the case of radio installations, whether or not they are intended to be connected to a public network.
As the standards and technical regulations approved at the West African Economic and Monetary Union (WAEMU) level, as well as the community accreditation system, apply in Guinea-Bissau, the conformity of imported goods with technical regulations can be certified by an accredited laboratory, with a certificate of conformity mark as proof. The Scheme for the Harmonization of Accreditation, Certification, standardisation and Metrology Activities within WAEMU is based on the principle of mutual recognition among Member States at three levels: recognition of technical regulations, national standards and specifications, recognition of conformity assessment procedures and their results. Support for achieving consistency of national regimes is provided by three technical structures, one of which is the West African Accreditation System (SOAC). The purpose of introducing the SOAC was to give Member States a single organisation for accrediting conformity assessment bodies (laboratories, inspection bodies and certification bodies). The SOAC signed a Mutual Recognition Agreement with the African Accreditation Cooperation (AFRAC) and the International Laboratory Accreditation Cooperation (ILAC) in May 2022.

According to Arts. 3 and 5 of Decree No. 22/2013, anyone wishing to subscribe to mobile cellular telecommunications services (including the acquisition of SIM cards) is obliged to identify themselves by registering their names and national identification numbers before the telecommunications operators.

The indicator "7.2.4 - Government Internet shut down in practice" of the V-Dem Dataset, which measures whether the government has the technical capacity to actively make internet service cease, thus interrupting domestic access to the internet or whether the government has decided to do so, has a score of 3 in Guinea-Bissau for the year 2024. This corresponds to "Rarely but there have been a few occasions throughout the year when the government shut down domestic access to Internet."
