As La Quadrature du Net noted in a statement, the cables « do not bring anything entirely new to our understanding of Acta« . However, they do reveal certain interesting details about the lengthy and secretive formulation of the agreement.
Cables from 2006, around the time that work on Acta began, showed that Japan resisted a World Trade Organisation legal attack on China, which is widely seen as a haven for intellectual property infringement — while groups such as La Quadrature du Net are most exercised by the online infringement aspects of Acta, the agreement is largely concerned with physical counterfeits.
