COP30 host Brazil has created 10 new Indigenous territories, with the climate summit hit by protests in recent days, Reuters reported.
The designation means the areas, including one in part of the Amazon, will have their culture and environment protected under Brazilian law - though this is not always enforced.
The move follows similar actions from President Luiz Inácio Lula da Silva, whose government recognised Indigenous possession of 11 territories last year.
"Each and every indigenous territory in Brazil is a reason to celebrate and is a reason for us to feel happy," Dinamam Tuxu from the group Articulation of Indigenous Peoples of Brazil (APIB) told the BBC at COP30, according to Reuters.
