The new conservative government of Argentina announced on Sunday that it will maintain its claim over the Falkland Islands, locking the country in dispute with Britain.

"Argentina renews its firm commitment to peacefully settling its differences, to international law and multilateralism, the foreign ministry under the country's new president, Mauricio Macri," according to a statement quoted in Yahoo! News' report from AFP.

For two months, Argentina and Britain warred over the rocky archipelago in 1982, the news outlet further reported. The battle killed 649 Argentine servicemen and 225 British. Decades after the Falklands War, both nations are still in a diplomatic dispute over the area's ownership.

Argentina's capital, Buenos Aires, "invites the United Kingdom to resume as soon as possible negotiations aimed at settling fairly and definitively, the sovereignty dispute over the Malvinas (Falklands) islands, South Georgia, South Sandwich islands and surrounding territorial seas," according to the statement, as reported by Yahoo! News.

Macri's country maintained its stand that Argentina inherited the Falklands from Spain when it acquired independence, Yahoo! News added. Britain, on the other hand, claimed that it has historically ruled the archipelago and that the residents of the island should have the right to self-determination.

Margaret Thatcher Stopped Argentina from Buying Modern War Weapons in Falklands War Aftermath

Newly released government files revealed that Margaret Thatcher prevented Germany and Italy from selling missiles and torpedoes to Argentina after the Falklands War.

Express.co.uk reported that in 1986, a confidential document from the Foreign Office urged Thatcher, Britain's prime minister at the time, to write to German Chancellor Helmut Kohl and request for reassurance not to sell weapons to Argentina.

As quoted by Express.co.uk, the document read: "The background is that Kohl gave the prime minister last year an assurance that the federal government would not permit the export to Argentina of AEG-Telefunken surface and underwater target (SUT) torpedoes while conditions in the South Atlantic remained unsettled."

The document also stated that the Foreign Office "have been seeking a similarly clear assurance from the Italians in respect of the comparable torpedoes" manufactured by Italy's Whitehead Moto Fides, the news outlet noted.

In a letter drafted by Thatcher addressed to Kohl, she said that there had been "little constructive response" from Argentina when it came to Britain's initiatives to normalizing relations, adding that the South American country's continued attempts to acquire modern arms is an indication that "it has not formally declared a cessation of hostilities," Express.co.uk reported.

Thatcher's diplomatic force seemed to have proved successful, given that no German or Italian weapons were sold to Argentina back then, Express.co.uk wrote.
