This explains it: <a href="https:&#x2F;&#x2F;www.reddit.com&#x2F;r&#x2F;PoliticalDiscussion&#x2F;comments&#x2F;35mers&#x2F;if_the_trans_pacific_partnership_is_such_a_great&#x2F;cr5rw6n" rel="nofollow">https:&#x2F;&#x2F;www.reddit.com&#x2F;r&#x2F;PoliticalDiscussion&#x2F;comments&#x2F;35mers...</a><p>Quoting a bit:<p>&gt; All treaties are generally negotiated in secret, not just trade treaties, because draft documents do not actually represent what any country is actually seeking but rather a position they are taking to secure the terms they want. Countries will always overreach during negotiations by asking for insane&#x2F;unrealistic things to be included such that the other countries involved are more willing to settle on a moderate position. Its precisely the same reason business deals, employment contracts and generally any other adversarial situation wont have working documents released publicly; it weakens the negotiation position for all sides to have a perfect understanding of the goals of the other side(s).
