Australia's largest business organisation has called for the government to open up the negotiation of trade deals such as the Trans Pacific Partnership.

As the Trade Minister Andrew Robb responded to criticism of his actions in keeping the text of the Trans Pacific agreement secret, the Australian Chamber of Commerce and Industry said it wanted negotiations to be monitored in real time by the Productivity Commission and wanted draft texts disclosed to registered community and business organisations as happens in the US.

Criticised for keeping the negotiations secret in a so-called health impact statement released by the University of NSW Centre for Health Equity Training Research and Evaluation, Mr Robb said the text of the agreement would be made public as soon as it was agreed between the 12 nations.
