Between 4 and 5 November 2005, the city of Mar del Plata hosted the Fourth Summit of the Americas. Although the themes were unemployment and poverty, most of the discussion was focused on the FTAA. The summit was a failure in this regard, but marked a clear split between the countries of the Mercosur, plus Venezuela, and the supporters of the FTAA, led by the United States, Mexico and Canada. FTAA negotiations have effectively stalled until at least the conclusion of the 2006 Doha round global trade talks.
