Make sense when we are on the wrong road? He says, that this Summit of the regional bloc, in Asuncion, showed it closer to Central America with the problem of Honduras than of the Rio de la Plata. Certainly, one Summit has been done of this regional bloc, precisely, XXXVII Summit of Presidents of MERCOSUR in Asuncion, Paraguay; on 23 and 24 July 2009, and as mercosurnoticias.com review it, acknowledged the guarani language as an official language of MERCOSUR together into Spanish and Portuguese. It should be noted that on Tuesday, April 28, 2009, the Parliament (Parlasur) MERCOSUR met in Asuncion; It had already approved unanimously the recognition of the Guarani language as an official language of MERCOSUR. That resolution should be ratified by the Member countries of the block on the occasion of this Summit of MERCOSUR Presidents XXXVII. It should be recalled that on 26 March 1991 in Asuncion (Paraguay), the Presidents of Paraguay, Argentina, Uruguay and Brazil; they signed the Treaty of Asuncion, which was constituted of the southern common market (MERCOSUR). The article 17 of the abovementioned Treaty States textually: the official languages of the common market are the Spanish and Portuguese and the official version of the working documents shall be the language of the host country of each meeting.It should be noted that at the time of the Treaty being signed, the Paraguay still had as an official language only to the Spanish, just a year later; i.e., in 1992, the constituent National Convention granted the rank of official language of the Paraguay alongside Spanish Guarani. That was also the reason by which the Guarani language had not been incorporated as an official language of MERCOSUR, in the Treaty signed in 1991, since it was not yet an official language, was only national language of the Paraguay.Tras the enactment of the new national Constitution of Paraguay on June 20, 1992, arose the first comments about the need to grant to the Guarani language range official MERCOSUR, since article 140 of the new Constitution recognized the Guarani as official language of the Paraguay alongside Spanish.This new scenario led to the submission of multiple requests national authorities – both specialized institutions and individuals – to order to start negotiations before the other members of MERCOSUR to achieve the Declaration of Guarani as official language of the same.
