ban on nuclear-weapon tents has been the topic of different fora for more than 25 years. Solutions to many problems regarding such a ban, including verification, have been found in the trilateral talks and at this Conference. Specific verification issues and other aspects of a CTBT were examined by the NTB Working Group in 1982 and 1985 and by the Group of Scientific Experts. To carry on these GE.85-65485 CD/629 page 2 activities in the absence of negotiations on a CTB would invariably mean that the Conference is used by some States as an alibi for the continuation of their testing programmes. The Group of Scientific Experts would thus become pointless, if certain States do not refrain from creating obstacles to practical negotiations. Its future should be related to a negotiating process on a nuclear test ban. For this reason, an international seismic monitoring network can be established only in conjunction with such a treaty. 5. Progress towards the complete cessation of nuclear-weapon tests can only be made in the framework of a pertinent negotiating process. The Conference, therefore, should be enabled to live-up to its negotiating role, as defined in paragraph 120 of the Final Document of the First SSOD, and establish an ad hoc committee to elaborate a treaty on the complete and general prohibition of nuclear-weapon tests. In this context, the People’s Republic ,of'Bulgaria and the German Democratic Republic would like to reiterate their view, expressed in document CD/194 of a group of socialist countries, that such a treaty should be aimed at the general and complete cessation of the testing of nuclear weapons by all States in all environments for all time. As far as the mandate for the committee is concerned, the two countries wish to reaffirm the proposal contained in document CD/522/Rev.l and they are equally prepared 
**Analysis**
The text appears to be discussing international diplomacy and negotiations regarding a nuclear test ban treaty. It mentions specific groups and organizations involved in the process, such as the Group of Scientific Experts and the NTB Working Group. The language used is formal and technical, suggesting that the topic is highly specialized and requires expert knowledge. The text also touches on the idea of verification and monitoring, which is a critical aspect of any international treaty.
