However, WTO Ambassador Crawford Falconer of New Zealand, the chairman of the WTO Agriculture Committee is hopeful, but says progress will depend on how WTO member nation's trade ministers move forward with the revised trade negotiating texts.

"It'll depend a bit on how the discussions go on agriculture as well as NAMA let alone what happens on other texts that may or may not emerge in the meantime," Mr Falconer says.

"I don't think anyone really knows what will happen after that point."

Last week Mr Falconer released the revised negotiating texts, saying the gap between several key agricultural issues had narrowed.

"Given that I don't believe that there are that many issues left in agriculture based on where the process has gotten us to this point, although hot spots will probably remain all the way to Ministers," he says.

"I don't think it's a long way away from being able to resolve it if you were only looking at agriculture.

"But of course nobody is only looking at agriculture."
