The text relating to the Trans-Pacific Partnership (TPP) trade deal has become one of the biggest secrets in Washington.
The TPP is a proposed regional regulatory and investment treaty. Put simply, it's a deal between participating countries intended to enhance trade and investment.
As of 2014, 12 countries have taken part in negotiations on the TPP: Australia, Brunei, Canada, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore, the United States, and Vietnam.
Implementation of the TPP is one of the primary goals of the trade agenda of the Obama administration in the US. The details of the TPP have not been made public, however.
What the public does know about the deal comes from three leaked chapters sent to WikiLeaks. And now WikiLeaks is looking to raise $100,000 towards a cash reward to anyone willing to reveal the rest of the 26 chapters.
The concerns are in large part down to the secrecy of negotiations, the agreement's expansive scope, and controversial clauses in drafts leaked to the public.
President Barack Obama has clashed with his own party over the deal as critics have been worried about the impact on jobs and civil liberties.
In January, WikLeaks published a chapter from the TPP related to the environment. Prior to that, in November 2013, it made public a draft of the agreement's intellectual property chapter, containing proposals that WikiLeaks founder Julian Assange said would 'trample over individual rights and free expression'.
The Guardian reports the latest leak concerns telecommunications services, an amendment that would standardize regulation of telecoms across member countries, according to WikiLeaks.
