At no time did England object to the Argentine settlement of the Malvinas, despite the fact that extremely important legal acts had taken place between the two countries, such as the signing of the Treaty of Friendship, Trade and Navigation of February 1825.
This instrument does not contain any British reservation whatsoever on Malvinas Islands, despite the action in 1820 and other acts that the Government had carried out and authorized regarding the islands.
In forcing any argument to seek to justify that Argentina did what it never did- i.e. drop the claim- the UK even distorts the scope of the 1850 Convention between Argentina and Great Britain. This agreement was meant to put an end to the naval blockade imposed by the UK and France in the River Plate and all its provisions relate to the need to solve the situation in the River Plate and bring back trade and political stability. It has no relation whatsoever with the Malvinas Islands. So much so that in 1849, after signing the Convention, Juan Manuel de Rosas referred to the sovereignty claim over the Malvinas Islands in his message to the Legislative House.
The issue remained unsettled and this was recognized by the British Foreign Secretary in 1849. Argentina, meanwhile, continued to raise the issue at different levels of government and it became a subject of debate in the Argentine Congress. In 1884, in view of the lack of response to the repeated protests, Argentina proposed to take the issue to international arbitration, which was also rejected by the United Kingdom without any reasons provided.
