The Pacific Network on Globalisation says Pacific countries need to be using a meeting between European Union and the region's parliamentarians to push for the EU to be more flexible on Economic Partnership Agreements.
African, Caribbean and Pacific countries and EU talks got underway in Port Moresby on Monday.
PANG says Pacific trade ministers want to rewrite their interim EPAs as they were signed under pressure that they would lose market share and suffer economic penalties.
Its coordinator Maureen Penjueli says the current hardline approach by the European Commission is inappropriate.
"We're looking particularly to this forum, the joint parliamentary assembly, for the European parliamentarians themselves to rein in the commission. Because we believe that the Commission to date [has used] well-documented pressure on developing countries to push them to sign."
