Various reports have raised concerns about the alleged presence of "uncontacted tribes" in an area of the Peruvian Amazon where the oil firms Repsol YPF and Perenco are operating. Perenco Peru is developing an area called "Block 67", and Repsol is developing "Block 39". The Business & Human Rights Resource Centre invited Repsol and Perenco to respond. Their responses are below, as well as a follow-up statement to Repsol by Survival. The first two items also raise concerns about the process involved in a report by the consultancy Daimi, commissioned by Perenco, which said that there is no evidence of uncontacted tribes in Block 67. We invited Daimi to respond but it did not do so.
