WTO: Ideas on helping WTO Doha negotiations forward -> freeze and reduce fish subsidies by 10% the first year

In a previous post I included a quote from a article of a former Indian Ambassador to the WTO, where he set out his views on the possible ingredients (fish not on the plate!) for salvaging the Doha Round.

In the mean time other articles have been published in the voexeu.org website. Some authors writing on the WTO Doha Round have proposed  that "middle trading powers" should 

"Freeze all harmful fisheries subsidies and offer to reduce them by 10% in the first year provided a critical mass of members do the same;"  Richard Baldwin  and Simon J. Evenett © voxEU.org

I wonder which countries the authors have in mind when writing about "middle trading powers"?
