India, Brazil and South Africa belong to the most intractable blocking actors in the Doha Round. In order to explain this posture, reference is frequently made to the lack of willingness to compromise on the part of the other central actors EU and USA. In addition, the three countries' interests in the construction of an alliance of the South are cited as motivation for blocking the negotiations. This paper, however, accepts that trade policy is a two-level game and shows that the configurations of national decision processes in India, Brazil and South Africa and the resulting influence of specific interest groups significantly contribute to consolidating the blockade position. Against this backdrop, the authors are sceptical about the prospects of a compromise solution to the Doha Round.
