Over the last few decades, the European Union (EU) has enhanced its role as a global actor in human rights broadly and disability rights, in particular. By concluding the United Nations Convention on the Rights of Persons with Disabilities (CRPD) in 2010 and assuming an obligation to promote disability rights externally under Article 32 CRPD, the EU has increasingly integrated disability rights into its external action to support the implementation of the CRPD in third countries. Among the broad spectrum of the EU’s relations globally, this thesis focuses on the EU's role as a promoter of disability rights in the European Neighbourhood Policy (ENP) and, particularly in its Eastern dimension, the Eastern Partnership (EaP). Arguably, establishing an area of prosperity around its borders to ensure its own stability and security remains one of the EU’s main objectives in its foreign policy. With this in mind, this thesis investigates the disability facet of the ever-evolving EU’s cooperation with the EaP countries – Ukraine, the Republic of Moldova (Moldova), Georgia, the Republic of Armenia (Armenia), and the Republic of Azerbaijan (Azerbaijan). Through the lens of the ‘global reach of EU law’ as a theoretical framework, it discusses which mechanisms and tools stimulate the transfer of EU disability norms into the legal orders of partner countries. To this end, conditionality and socialisation, as the main modes of the EU’s governance in the EaP, are scrutinised to investigate how they support the reach of EU disability norms. It then examines how EU disability norms transfer impacts the national legal orders of the EaP countries and presents a case study of Ukraine.
