No, unfortunately, I don't. I don't see any incentive with this agreement to improve corporate behaviour within Panama. Rather it's a reinforcement of the status quo, which to date has not been very beneficial to indigenous peoples in Panama. They have suffered tremendous repression over the course of the last couple of years. They've lacked effective access to democratic channels to have their disputes solved peacefully and they continue to complain about the Panamanian government's failure to follow through on its obligations to ensure social, educational, and other benefits for their communities, regardless of whether or not mining is happening in their territories.
