 On the level of international relations , Mariano Moreno rejected slavery in Brazil , a neighboring Portuguese colony . He proposed to distribute large numbers of Gazeta de Buenos Ayres newspapers , filled with libertarian ideas and translated into Portuguese , and provide military support to the slaves if they should riot . He considered the risk of a complete Spanish defeat in the Peninsular War or a restoration of absolutism great menaces , and regarded Britain as a potential ally against them . During a conflict , Britain would be able to provide them with weapons and other goods not produced locally . Critics of Moreno consider him an Anglophile because of this proposal , but the same document also warns against the risk of allowing Britain too much influence in national economy . He criticized the relationship between Britain and Portugal , considering that Portugal was subject to a " shameful slavery " to Britain , and that British influence in Brazil was so high that the Portuguese colonies might eventually become British ones . Moreno held the same ideas about being simultaneously friendly and cautious with Britain in the pages of the Gazeta newspaper .
