Washington (AFP) - The United States handed thousands of documents Friday to Argentina on disappearances by the former US-backed military dictatorship, completing Washington's biggest-ever transfer of documents to another government.
With a ceremony at the National Archives, the grand Greco-Roman building in central Washington that is home to the US Constitution and other founding documents, the United States fulfilled a pledge made three years ago by then president Barack Obama when he honored the victims of the 1976-1983 military regime on a visit to Buenos Aires.
Receiving the files from the archivist of the United States, Argentina's Justice Minister German Garavano said the documents "will be fundamental to justice."
"This is good news for the Argentine people to learn from the past and not repeat this in the future," he said.
In an accompanying letter to his Argentine counterpart Mauricio Macri, President Donald Trump said the declassification "demonstrates our shared commitment to promoting open and transparent government."
"It also reflects the importance that the United States places in its relations with Argentina," said Trump, who visited Buenos Aires in late 2018.
"My hope is that access to these records provides the people of Argentina information to help in the healing process."
The State Department said that the United States was releasing 6,000 new documents, bringing the total handed over through the project to 50,000 pages.
The files include memoranda and correspondence from the State Department, CIA and other agencies that detail what the United States knew about the abuses in Argentina.
Some 30,000 people were killed or remain missing from Argentina's "dirty war," when security forces and right-wing paramilitaries hunted down any perceived leftists.
The military ousted leftist president Isabel Peron in 1976, one of a series of coups in Latin America supported by the United States under top diplomat Henry Kissinger as part of the worldwide offensive against communism.
Trump has sworn anew to destroy socialism, including seeking to oust Venezuela's President Nicolas Maduro. But he did not stop the declassification amid appeals from Macri, a conservative who enjoys warm relations with Trump.
The National Security Archive, the history project at George Washington University that frequently takes legal action to declassify documents, praised the comprehensiveness of the release.
"The Argentina Project represents a new model of declassification diplomacy, and more," said Carlos Osorio, an analyst at the archive.
