The Ibero-American Air Convention - 1926

 In 1919, Spain and all the other ex-neutral governments in World War I had been invited to adhere to the Paris Convention. Spain had declined to do so, partially due to Article 34 of this Convention related to the uneven equivalency between parties. Moreover, Spain withdrew from the League of Nations in 1926, its claim for a permanent seat on its Council having been rejected.

To do so – a fazê-lo           due to – devido a       moreover – além disso

Uneven equivalency – equivalência desigual/irregular 

Withdrew (withdraw) – retirou (retirar)   claim – pedido, reivindicação

Following the growth of aviation activity between Spain and South-America and as a result of the failure by the USA and most Central and South American States to adhere to the Paris Convention, Spain decided to initiate a diplomatic counteraction and invited all Latin American and Caribbean States and Portugal to the Ibero-American Conference to be held in Madrid from 25 to 30 October 1926.

Counteraction – ação contrária/ de oposição   To be held in – a ser realizada em

At the end of a Conference, the Ibero-American Convention on Air Navigation (called Convenio Ibero Americano de Navegación Aérea, or CIANA, also called the Madrid Convention) was created. This convention differed from the Paris Convention in that it differently took account of the principle of the equal voting rights of its members (Article 34) and the right for a Contracting State to permit the flight above its territory of an aircraft that did not possess the nationality of a Contracting State (Article 5). Whereas 21 States (Spain, Portugal and 19 Latin American countries) signed this Convention on 1 November 1926, but only 7 States (Argentina, Costa Rica, Dominican Republic, El Salvador, Mexico, Spain and Paraguay) deposited their instruments of ratification.

The Ibero-American Air Convention was modelled after the Paris Convention and its wording was virtually identical in most of the articles; only the offensive articles of the Paris Convention were significantly amended to assure the equality of States and eliminate any discriminatory implications concerning the States. 

Amended – alterado, corrigir   To assure – assegurar, garantir

In most of – na maior parte de  Concerning – relacionado a , relativo a

Argentina and Spain renounced the Convention by 1933 and joined the ICAN; the Madrid Convention never came into force. It was no more than the result of political posturing of Spain trying to assert leadership in Latin America.
