text: Ad hoc Group of Scientific Experts to Consider International Co-operative Measures to Detect and Identify Seismic Events. We would like to welcome the successful conclusion of the twenty-ninth session of the Group. The Chinese delegation expresses its appreciation of the constructive work of the Group of Scientific Experts. We are also appreciative of the positive efforts made by the Chairman of the Group, Dr. Dahlman of Sweden, and its Co-ordinator, Dr. Basham of Canada. En passant I would like to say that the appropriate departments and experts in our cohntry are seriously considering participation in international data exchange experiments on seismic events. We have noted that the meeting of the Group has decided to postpone phase three of the large-scale experiment. This will lead to better results in the experiment on a larger scale. The PRESIDENT : You will recall that at our last plenary meeting, I announced that we would take action today on the recommendations contained in paragraphs 9 and 13 of the progress report of the Ad hoc Group of Scientific Experts to Consider International Co-operative Measures to Detect and Identify Seismic Events. In connection with paragraph 9, the Chair circulated, at the plenary meeting held on 5 April, the draft of a letter that I as President will address to the Secretary-General of the World Meteorological Oganization in connection with the participation of a member of the Ad hoc Group in the next session of the WMO Commission for Basic Systems Working Group on the Global Telecommunication System. It was noted at that plenary meeting that, if no objections were raised before today's plenary meeting, the letter would be sent as drafted. No objections have been received and, accordingly, I shall proceed as indicated. CD/PV.551 16 (The President )
analysis: The text appears to be related to an international organization, likely the United Nations, discussing the work of an Ad hoc Group of Scientific Experts focused on detecting and identifying seismic events. The language used is formal and official, suggesting a technical or scientific topic. The mention of a draft letter to the Secretary-General of the World Meteorological Organization and the reference to a Commission for Basic Systems Working Group on the Global Telecommunication System further support this hypothesis.
