Thanks to its regulatory powers, robust digital economy, and active foreign and security policy, the European Union is one of the key players in cyberspace. The EU strongly promotes the position that international law, and in particular the United Nations (UN) Charter, applies in cyberspace. As a complement to binding international law, the EU endorses the voluntary non-binding norms, rules and principles of responsible State behaviour that have been articulated by the UN Group of Governmental Experts. It also encourages the development and implementation of regional confidence building measures, both in the Organisation for Security and Co-operation in Europe and other regions. On a bilateral level, the EU has established cyber dialogues with strategic partners to reinforce the exchange of good practices, lessons learnt and further the idea of responsible state behaviour in cyberspace.

Overall, Cuba's internet and social media penetration is limited due to access limitations, slow network speeds, and high costs, resulting in a rather slow internet adoption. The Cuban government has attempted to expand public Wi-Fi hotspots launching 3G and 4G mobile networks. Despite these efforts, internet access in Cuba remains expensive and limited compared to other countries in the region.
According to a 2021 report by Freedom House, the Cuban government uses a range of tactics to restrict online speech, including censorship, surveillance, and intimidation of online activists. The report notes that online criticism of the government can result in arrest and imprisonment.

El Salvador is known for its adoption of Bitcoin as a legal tender in 2021. El Salvador’s internet penetration rate stood at 50.5 % of the total population at the start of 2022, with over 4 million social media users. El Salvador is making important progress towards digitalisation in terms of infrastructure capacity and reliability, but there are still challenges to overcome, such as access and affordability to internet connections, especially in rural areas. Regarding data protection, El Salvador still lacks a comprehensive data protection law, although the country has made improvements in the past years.

Under the auspices of the UN, the EU and its Member States have consistently reaffirmed that a universal cyber security framework can only be grounded in existing international law, including the Charter of the United Nations in its entirety, international humanitarian law, and international human rights law. 
Addressing issues as to how existing international law and international humanitarian law, including the principles of humanity, necessity, proportionality and distinction, apply to the use ICTs by States is necessary to increase accountability and transparency. International humanitarian law is fully applicable in cyberspace and this should not be misunderstood as legitimising the use of force between states in the cyber domain. The EU has typically opposed calls for the need to adapt existing international law as a means to develop a new legal instrument for cyber issues.

It's worth noting that while Cuba has participated in international discussions and informal negotiations related to cybersecurity, it has not signed or ratified binding agreements regarding cyberspace or digital rights. Its government has also been criticised by human rights groups for its restrictions on internet access and online freedom of expression, which have limited its ability to fully engage in these discussions.

El Salvador has supported, along with several other states, a Russian-backed proposal to develop a new binding legal instrument to govern responsible state behaviour in cyberspace. It’s the Salvadoran position that the absence of legislation is the main obstacle towards fighting cybercrime internationally.

Since 2014, the EU’s ambition has been to act as an ‘honest broker’ on multilateral discussions surrounding issues of cyber governance and norms of responsible state behaviour, aiming to ensure the support and partnership of proactive players in the context of the global debate. The EU has long promoted the need for voluntary, non-binding norms. It believes that norms crystallised under the UN GGE process should generally not be revisited and that progress should be made on matters relating to their implementation. 
Within the OEWG, the EU advanced a suggestion to develop a global repository of existing practice within the United Nations, which would enable UN member states to showcase how they are implementing the voluntary norms of responsible state behaviour, confidence building and other measures.

Cuba has been represented in the United Nations Group of Governmental Experts (UN GGE) on Developments in the Field of Information and Telecommunications in the Context of International Security. It participated in multiple sessions of the UN GGE and has made contributions as part of the NAM (Non-Aligned Movement), a group of countries that are not formally aligned with any major power bloc. As such, a 2017 statement by Cuba emphasised the need to avoid a ‘state militarisation’ of cyberspace and concentrate on peaceful settlement of disputes and conflict prevention. In 2019, for instance, Cuba called for the development of a safe cyberspace environment that can promote well-being, knowledge and human development.

El Salvador has been actively involved in promoting a safe cyberspace. The Latin American country, back in 2015, signed a memorandum of understanding with the UN Office on Drugs and Crime to support the fight against cybercrime, with training in capacity building, prevention and cooperation.
El Salvador has expressed views on the use of information and communications technologies for criminal purposes at the UNGA. As part of their statement, it was noted the lack of regulation obliging network administrators of public, private, or non-profit institutions to establish, maintain, and safeguard the connection logs of their internal clients, which can be exploited for the commission of traditional crime and cybercrime.
As part of the OEWG discussions, El Salvador has identified the norm regarding ICT product supply chains as the most important for states, in addition to proposing that the OEWG highlights the efforts and progress that countries are making in cybersecurity, making the spirit of cooperation in this area clear.

The EU places great importance on cyber resilience and capacity building. Internally, the Union has built a robust legal acquis in relation to the resilience of critical infrastructures, the cornerstone of which rests upon the 2016 Network and Information Security (NIS) Directive and the 2013 and 2019 Cybersecurity Acts. This legal meshwork seeks to integrate cybersecurity into all elements of the supply chain and introduce soft law mechanisms like the EU cybersecurity certification scheme. In doing so, it harmonises national cybersecurity capabilities, cross-border collaboration and the supervision of critical sectors across the EU. 
In the coming months, the Commission intends to add upon the existing cyber-acquis by introducing an array of new initiatives, such as the updated NIS Directive (the so-called NIS2), a proposal on a Critical Entities Resilience (CER) Directive, and a plan to launch a network of Security Operations Centres across the Union. The aim is to create a Union-wide ‘cybersecurity shield’ that will facilitate the detection of cyberattacks and provide an impetus for proactive action. 
This internal buildup of capabilities is supplemented by the development of a specialised ‘cyber diplomacy toolbox’ that allows the Union and its Member States to address cyber incidents through various joint policies, from cooperation and stabilisation measures to restrictive measures and attribution.

Cuba launched its first strategy on cybersecurity in 2019, emphasising the need for 'cybersecurity and cyber resilience' in the face of potential threats to national security and the economy, as well as protecting critical infrastructure. The resolution also focused on capacity-building and training in cybersecurity and cyber resilience, both within the government and in the private sector.

El Salvador has taken steps towards addressing cybercrime by establishing a Cybersecurity Policy which aims to ensure the resilience and security of strategic assets. It lays out criteria to develop cybersecurity capacities aimed at protecting critical infrastructure, strengthening response mechanisms, and developing technical and administration skills so that the public and private institutions in El Salvador as well as citizens are aware of cybersecurity and risks related to the use of information technologies.

The EU has been an early champion of the Budapest Convention signed under the auspices of the Council of Europe, given the overlapping membership of the two organisations. Much of the EU’s cyber diplomatic efforts have focused on promoting the Convention as the main instrument of choice for fighting cybercrime on a global level. EU member states have consistently opposed Russian bids for replacing this regime with another legal framework. 
The Union is represented in the recently constituted Ad Hoc Committee established by UNGA resolution 74/247 by its Member States and is currently focused on ensuring that the process is inclusive, transparent, consistent with the progress of the UNGGE and OEWG processes, and committed to legal consistency.

Cuba is not a signatory of the Budapest Convention on Cybercrime and has developed its own domestic legal framework in the matter, such as Decree-Law No. 360/2019 which covers a wide range of crimes related to information and communication technologies. In an ongoing debate surrounding this new legislation, critics say that the law could be used to suppress dissent and limit freedom of expression online.

El Salvador has its own legal framework regarding cybercrime, dating back to 2016, but updated during Bukele’s government, called Special Law against Cybercrime and Related Offenses. The bill establishes a series of crimes related to computer systems and electronic communication, such as unauthorised access to computer systems, the production and dissemination of malicious software, and computer fraud.
