On August 26, 2021, the Shuar Arutam People, along with 136 other Ecuadorian and Canadian organizations, sent a letter to Canada's Ambassador to Ecuador, Sylvie Bédard, denouncing alleged corporate abuses committed by the Canadian Mining Company Solaris Resources in the context of its Warintza project; including the promotion of community division, intimidation and militarization of the Shuar Arutam territory and a death threat against the president of the Shuar Arutam People (PSHA), Josefina Tunki, and her colleagues.

The Shuar Arutam People also called on the Ecuadorian president Guillermo Lasso to suspend large-scale mining activities carried out by Solaris in their territory and asked the Inter-American Commission on Human Rights, the Special Rapporteur on the Rights of Indigenous Peoples, and other United Nations bodies to "demand the Ecuadorian government to strictly comply with the human rights of the PSHA and its 47 communities against the serious denunciations and threats".

The BHRRC invited Solaris Resources to comment on the allegations made by the Shuar Arutam People Association and the company did so.
