the work on a nuclear item which falls to the responsibility of the Conference on Disarmament. We are satisfied with the progress achieved so far in the experiment on the exchange of level II data. Wide experience has been gained in this process, which is valuable for its continuation and successful conclusion. At this juncture, I should like to express our gratitude and appreciation to all scientists from the countries participating in GSETT-2 for the purposeful work accomplished by them and, in particular, to Dr. Dahlman (Sweden) and Dr. Basham (Canada) for their dedicated activities in this endeavour. As it was stated by Dr. Ola Dahlman on 5 April 1990 here in this forum, the Group of Scientific Experts, during its spring session, carried out comprehensive work with a view to solving manifold organizational and scientific and technological questions connected with this experiment. We welcome the activities planned to settle several problems that remain pending, especially in connection with the processing of the amount of transmitted data, which was much larger than anticipated. The co-operation with WMO will be conducive to finding answers to the unresolved questions concerning data transmission. We agree with the revision of the preliminary schedule for GSETT-2, as well as with paragraphs 9 and 13 of the progress report on the twenty-ninth session of the GSE. Our Group considers the broadest possible participation by States in GSETT-2 to be of major importance. This would help improve the conditions for testing the concept for a global data exchange system specified in the GSE's fifth report in a realistic environment. So far 21 countries, some of them having strongly differing starting positions in terms of science and technology, personnel and finance, have successfully participated in the experiment. We welcome the fact that more States, among them countries from our Group, have expressed their intention of taking part in future GSETT-2 
**Analysis**
The text discusses the progress and future plans of an experiment related to the exchange of level II data, specifically in the context of the Conference on Disarmament and the Group of Scientific Experts (GSE). The language used is technical and scientific, and the goals of the experiment are to test the concept of a global data exchange system. This suggests that the text is related to scientific and technological issues, rather than economic or social development.
