Disarmament and would urge all the nuclear Powers to take part in this work. Thirdly, in our view, a global seismological network would have to play a central role in verifying a test ban. such a network should ensure a reliable international data exchange on the basis of the most modern technology. In order to shed further light on how such a network would operate, Norway organized earlier this year a Conference on Disarmament workshop in Oslo on seismological verification of a nuclear-test ban. our research indicates that some technical problems still remain to be solved. The problems relate in particular to detection and identification of very-low-yield explosions as well as explosions that produce very weak signals. Before leaving the question of nuclear arms control and disarmament, I should like to state our position regarding a nuclear freeze. Norway will support a freeze on nuclear weapons, on the condition that a nuclear-arms freeze would be NR/plj A/C.l/40/PV.B 18 (Mr. Froysnes, Norway) agreed, balanced and verifiable. Furthermore, it can be meaningful only in the context of negotiations on substantial reductions in nuclear weapons. Sixty years ago we saw the conclusion of the Geneva Protocol prohibiting the use of chemical weapons. Today we are faced with the acute danger that that prohibition might be eroded. It is a matter of grave concern -and it must be strongly condemned -that chemical weapons .have recently been used in some areas of conflict. As the Geneva Protocol contains no verification machinery, Norway has supported the development of procedures within the United Nations to investigate possible violations of the Geneva Protocol. such procedures have now been developed. The negotiations in the Conference on Disarmament have proved that it is desirable to incorporate a prohibition on use in the new chemical weapons convention. Such a convention would constitute a comprehensive and global ban on 
**Analysis**
The text discusses disarmament, nuclear arms control, and the prevention of the use of chemical weapons, which suggests a focus on international security and diplomacy. The text also mentions the development of a global seismological network and verification machinery, which indicates a connection to science and technology.
