The purpose of this paper is to examine mechanism of Europeanisation trough the creation process example of a new wine law in Bosnia and Herzegovina (BiH), combining domestic wine regulations and EU legislative frameworks. We will analyze criteria and implications of Europeanization process, focusing on mechanism of assistance to candidate and pre-candidate countries. The aim is to understand the genesis of the conflict that hinders the development process and represents a barrier to trade liberalization. Adoption of law in BiH, as well as ordinances and regulations for its implementation and enforcement, is a precondition for a harmonized legal framework and competitive rules for the agriculture sector. For the analysis, we used dimensions of integrations and institutionalism theories as lenses to explore this processes. This approach is the one of the theoretical perspectives that has won converts and provided in many cases a useful tool for analyzing EU integration.
