Digital protectionism, characterized by the adoption of policies and regulations that prioritize national interests in the digital economy, is becoming increasingly prevalent in both the European Union (EU) and the United States (US). This trend reflects broader geopolitical, economic, and technological shifts. Measures such as data localization requirements, data transfer restrictions, and stringent privacy provisions, are reshaping the global digital landscape. This paper will explore the potential rise of digital protectionism in the EU and the US, analyzing its drivers and implications for global digital governance. In the EU, digital protectionism often takes the form of stringent privacy laws like the General Data Protection Regulation (GDPR), data sovereignty initiatives, and legislative efforts like the Digital Markets Act (DMA) and the Digital Services Act (DSA). These measures are frequently seen as aiming to curtail the dominance of non-EU tech giants. In the US, digital protectionism manifests primarily through measures such as export controls on advanced technologies, increased scrutiny of foreign investments in critical tech sectors, and state-specific privacy laws. The paper will define and conceptualize digital protectionism in the context of modern regulatory frameworks, identify legal and policy measures that reflect protectionist trends in the EU and the US, and analyze the implications of digital protectionism for international trade and innovation.
