The Rio Group has issued statements on the Malvinas Islands Question since 1993. On the occasion of the treatment of the question by the Special Committee on Decolonisation of the United Nations and the Fourth Commission of the General Assembly of the United Nations, the representative of the country occupying the Group Secretariat that year intervened in the debates on behalf of the Rio Group.
On 10 May 2005 the Rio Group issued a declaration supporting the legitimate rights of the Argentine Republic in the sovereignty dispute and expressed its concern over the inclusion of the South Atlantic islands in Annex II to the Treaty establishing a Constitution for Europe of 29 October 2004. Copies of this declaration were submitted by the Argentine embassies to foreign ministries in all the European Union Member States and to European Union authorities.
On 2nd March 2007, the Rio Group issued this statement:
"The Heads of State and Government of the Rio Group reaffirm their support to the legitimate rights of the Argentine Republic in the sovereignty dispute with the United Kingdom about the Malvinas Question."
They remind the regional interest that the Governments of the Argentine Republic and the United Kingdom of Great Britain and Northern Ireland resume negotiations in order to reach as soon as possible a fair, peaceful and lasting solution to the sovereignty dispute about the Malvinas, South Georgia and South Sandwich Islands and the surrounding maritime areas, according to the relevant resolutions and declarations of the United Nations and the Organization of the American States.
