There is no democratic process in international treaties and agreements and only a naive person would suggest there was. In international trade, as in any business agreement or contract negotiation, both parties are out to get as much from the other side in the agreement as they can while giving up as little as possible. And as negotiations proceed it's common for things to be included in the bargaining that the proposer has no intention of actually giving away or accepting ... it's just part of the negotiations. Open the negotiations up publicly and no deal would ever be reached because neither side would be allowed to compromise.
