The Pacific Network on Globalisation or PANG has accused the Australian government of deceit as it promotes a proposed new trade deal.

Negotiations on PACER Plus may get the green light at this week's Pacific Islands Leaders Forum in Cairns but there is anger that Fiji could be excluded from the discussions.

Australian Trade Minister, Simon Crean claims the negotiations can proceed without Fiji because PACER Plus is not related to the earlier PACER deal made exclusively by the island countries.

Crean claims it was a completely separate agreement.

But Law Professor, Jane Calsey, speaking for PANG, said all the previous discussions on PACER Plus including as recently as last month have been under the umbrella of the PACER deal.
