Norway has agreed to return thousands of artefacts taken from Chile's Easter Island by renowned Norwegian explorer Thor Heyerdahl in 1956.
The agreement was signed by his son on behalf of Oslo's Kon-Tiki museum and Chile's culture ministry in Santiago.
The artefacts include carved pieces and human bones from the Pacific island.
In 1947, Heyerdahl became famous for skippering a tiny balsawood raft, the Kon-Tiki, on a 6,000km (3,728 miles) journey from Peru to Polynesia.
His expedition proved, he said, that ancient cultures could have sailed to, and populated, the South Pacific.
Later DNA tests suggested that the islands were settled by migrant populations from South East Asia.
Heyerdahl subsequently made a number of voyages around the world, including his expeditions to Easter Island (or Rapa Nui) in 1955-56 and again in 1986-88.
Heyerdahl conducted the first co-ordinated excavations on the remote island whose many carved heads stand guard over the Pacific.
The explorer and ethnographer died in 2002, aged 87.
What about the deal on the artefacts?
It was signed in Chile's National Library in Santiago.
Heyerdahl's son, Thor Heyerdahl Jr, says "the repatriation is a fulfilment of my father's promise to the Rapa Nui authorities that the objects would be returned after they had been analysed and published", he is quoted as saying by the AFP news agency.
Kon-Tiki museum director Martin Biehl said "our common interest is that the objects are returned and, above all, delivered to a well-equipped museum".
The whole process "will take time", he said, without giving any further details.
After the signing ceremony, Chilean Culture Minister Consuelo Valdes stressed that "as a ministry we have the mission to respond to the just demand of the Rapa Nui people to recover their cultural heritage".
Chile is also demanding that London's British Museum return the figure of Hoa Hakananai'a, an imposing basalt statue from Easter Island.
