147. The representative of Chile said that, in response to the European Communities' comment that TN/C/W/52 had taken on board the issue of special and differential treatment, several delegations, from developing countries in particular, had spoken in favour of the joint proposal in the context of costs and S&D, because it basically contained S&D in the form of its strictly voluntary nature. This issue was also related to the two principal issues of legal effects and participation and his delegation would therefore appreciate hearing more from the European Communities on S&D and on the costs that the TN/C/W/52 proposal involved. It would be useful to have a more elaborate written proposal so that these issues could be looked into.
