Review: Impact of bilateral trade on the promotion of animal welfare rules. The case of trade relations between the European Union and Mercosur.

• The paper examines the trade impact on spreading EU values on animal welfare. • It focuses on major legal topics: intensive breeding, transport, slaughter methods. • Firstly, EU standards are identified and explored in relation to the main issues. • Secondly, Argentina and Brazil are analyzed as Mercosur's main trading country. • The analysis shows that both Argentina and Brazil adopt rules "mirroring" EU law. The paper analyzes the impact of trade relations between the European Union (EU) and Mercosur with its member states (Argentina, and Brazil, in particular), on the adoption of legislation on animal welfare inspired by the EU model. In the first part, the paper focuses on the historical roots of the European framework, which led "animal welfare" to become an EU value. Then, it briefly explores the EU legal instrument dedicated to breeding, transport and commercialization of animals, identified as core issues when dealing with international trade. Finally, it examines how Argentina and Brazil have adapted their national rules to the European model, thanks to a "mirroring" legislation strategy. In conclusion, the analysis shows how trade relations with the EU have an impact on the worldwide diffusion of European standards. [ABSTRACT FROM AUTHOR]
