A new diplomatic spat has erupted between Argentina and the United Kingdom in Buenos Aires after London has accused Buenos Aires of violating the terms of a new deal to control the Falkland Islands when Argentina’s flag was flying from the UK in the same position as well as the Las Malvinas in Argentina.
There are long-standing differences over the sovereignty of the South Atlantic archipelago which are known as the Falkland Islands in the UK and Las Malvinas in Argentina.
The Argentine officials said that the banner had been held during a public event related to the Falkland Islands and that it had sent political messages that went against bilateral understanding, which is designed to prevent taking sides in the sovereignty conflict. Argentina’s Foreign Ministry said it was an affront to dialogue between the two countries.
The United Kingdom has not indicated that the banner violates any of those agreements and the British government has maintained that the Falkland Islands are a British Overseas Territory. British officials have always said that the islanders have the right to decide their own political future through self-determination.
The Falkland Islands have been in the centre of a sovereignty dispute for decades. Argentina says the islands were illegally occupied by Britain in the 19th century and believes they are an integral part of its own territory.
But the UK says it has administered the islands since 1833 and is convinced Falkland Islanders want to remain under British rule.
The issue is still very much alive in Argentina, where the Falklands War of 1982 is still a defining national event. The 74-day conflict killed more than 900 people before British forces regained control of the islands. Since then, relations between the two countries have often deteriorated whenever sovereignty issues come up.
Argentina has repeatedly urged the UK to resume negotiations under United Nations resolutions that encourage dialogue on the sovereignty dispute. But Britain insists that there will never be any talks about sovereignty at all unless the islanders want it.

The recent spat over the banner may seem symbolic, but diplomats say that such incidents weigh very politically. Public displays, official statements and commemorative events related to the Falklands are also flashpoints because both governments are very careful about their position.
Experts say the renewed row won’t result in immediate policy changes but it underscores how sensitive the Falklands conflict remains after four decades of war. Even the most insignificant incidents of domestic dispute and international law can quickly go global as national identity, historical claims and international law collide.
The Falkland Islands remain one of the most enduring territorial disputes in the world.
In the long run, this is going to be one of the most important territorial disputes in Argentina-UK relations, whether it is through diplomatic or political conflict that will not change or change, that can remain a part of Argentina-UK relations for years to come.
