Having reviewed the letter from OT Watch, we note that much of their statement refers to activities and events that in no way involve Rio Tinto or the Oyu Tolgoi project. We are happy to respond to those parts of the letter that are relevant to us and upon which we can factually comment. Broadly, these are concerns about the Environmental Impact Assessment, the water study, the integrity of the feasibility study, the application of OECD guidelines and the fairness of benefit sharing arrangements of the Oyu Tolgoi project.
