It seems that the Negotiating Group on Rules met recently. This is what the International Centre for Trade and Sustainable Develoment (ICTSD) is reporting in "Bridges Weekly Trade News Digest" (Volume 14, Number 44, 22 December 2010).
According to ICTSD Delegates discussed papers from Korea (TN/RL/GEN/168), Brazil, India, China and Mexico (TN/RL/GEN/163) which I discussed in my post of 13 February 2010, and Australia (TN/RL/GEN/167).
I assume that this was an "informal" meeting as no official record has been published.
