(en) The main objective of this thesis was to analyse the changes to Romania’s foreign policy towards Moldova as a result of the impact of its EU accession process. The thesis argued that upon Romania’s EU accession in 2007, the EU continued to cause the re-adjustment and re-formulation of Romania’s foreign policy towards Moldova. This case study was particularly relevant in highlighting the EU’s impact on national foreign policy due to the complex nature of Romania-Moldova relations resulting from a shared history, language and culture. The research was focused on the years 2001 through to 2009, considering that starting with 2001 the causal effect between the EU accession process and the formulation of Romania’s foreign policy could be more clearly established. The thesis conceptualised the impact of the EU on Romania’s foreign policy as a process of Europeanisation whereby Romania adapted its foreign policy towards Moldova to the exigencies of the EU accession process and EU membership. In doing so, Romania’s underlying aim was to further its chances of accession to the EU and equally, to develop more effective bilateral relations with Moldova. The thesis also found evidence that following Romania’s entry in the EU, Romania continued to Europeanise its foreign policy towards Moldova. The process of Europeanisation was thus maintained partly due to EU membership constraints and to the new opportunities that EU membership offered to Romania to shape EU policy on Moldova, thereby increasing the effectiveness of its bilateral policies towards Moldova.
