Greenpeace CTBT Updates
Updates from the Conference on Disarmament
9th June 1996

An important address at Thursday's Plenary meeting was the statement by Ambassador Sha Zukang of China in which he set out his country's current position on scope and peaceful nuclear explosions, entry-into-force, aspects of the preamble and the trigger mechanism for on-site inspections.

Meanwhile, the work of the ad hoc Committee on the Nuclear Test Ban has proceeded largely through a new mechanism of 'Moderator Groups' dealing with the major outstanding issues such as composition of the Executive Council, international monitoring system and international data centre, preamble and review, entry into force and on-site inspections. Depending on the issue, work has variously utilised the Chairman's draft CTBT text and also the Rolling Text.

The five Nuclear Weapon States continue with their private discussions on the major issues, but have not yet reached agreement amongst themselves.

1. Scope


The only significant new development on scope this week came on Thursday in China's statement to the Plenary, where they suggested a compromise related to so-called 'peaceful nuclear explosions' (PNEs). China had been discussing the proposal informally for some time, but had not made any formal proposal. Although variously interpreted as major development, the statement did NOT commit China to the true zero-yield option, originally formulated by Australia and included in the Chairman's draft CTBT text.

China’s indication that it could accept a temporary ban on PNEs provided that a specific provision is included in the treaty to require the possibility of permitting these in future, is to be considered by a Review Conference of the Parties (provision is made for a first conference to review the treaty ten years after it enters-into-force, with further review conferences at ten-yearly intervals thereafter).

It is important to note that China stated that only AFTER consensus was reached on its proposal for reviewing PNEs, would China be in a position to "favourably consider" the Australian proposal on scope.

While China's proposal is regarded by many as a 'face-saver', opposition to a specific reference to PNEs in the review remains strong, especially in the absence of a formal commitment yet to the Australian scope proposal. As review article in the Chairman's draft CTBT text, would allow any aspect of the treaty to be raised at a review conference, there seems to be no need for a specific provision for PNEs for China, and by including such a provision, PNEs would be given a too prominent status in the treaty.

2. Preamble and Review


The Moderator Group's discussion on Preamble and Review has seen vehement exchanges on the use of the Chairman's draft CTBT text and the Rolling Text.

2.1 Preamble


China, Pakistan and India are reportedly unhappy with the extent to which disarmament issues are reflected in the Chairman's draft text. Ambassador Ludwik Dembinski of Poland also mentioned in Thursday's Plenary that the Chairman's draft CTBT text could be improved by "...Preamble language that is perhaps less timid about the non-proliferation content of the CTBT".

China has indicated on Thursday that it agrees to withdraw its proposal for an article on negative security assurances, but "insists" that this idea be reflected in the Preamble.

2.2 Review
Reportedly, there is a lack of willingness to discuss the provisions of the review article until there is more clarity in what will be included in the preamble.

As noted above, China's proposal in Plenary was to have a special provision included in the review on the question of PNEs. However, the exact nature of the provision it is proposing remains unclear. From China's speech, it would appear to be proposing that a decision on PNEs would be taken by consensus and that some details on developing procedures for PNEs would need to be incorporated.

3. Verification


The Moderator Group discussions on the international monitoring system and the international data centre (IMS/IDC) are being based on the Chairman's text with minor details being worked upon.

The triggering mechanism for on-site inspection (OSI), especially the role of national technical means (NTMs) of verification remain problematic. Although Pakistan, India and China have accepted that technical data obtained through NTMs can be introduced in support of an OSI, they wish to see agreement needed by a two-thirds majority of the Executive Council before an OSI could be initiated. The United States is equally opposed to having to get a simple majority go-ahead from the Executive Could before initiating an OSI. Something along the lines of the provisions contained in the Chairman's draft CTBT text appear to be an appropriate middle-way.

Some outstanding difficulties remain with the provisions on managed access and overflights which could result in further weakening from the Chairman's draft CTBT text.

4. Entry-into-Force


This remains a deeply problematic issue. The United Kingdom, Russia and China continue to insist that whatever formula is used, there needs to be an explicit requirement for ratification by all 5 nuclear weapons states and the three 'threshold states' before the treaty can enter-into-force. Other countries, are concerned about having the treaty "held hostage" to the ratification of a state or group of states and also in formally recognising threshold states as such in an international instrument. These countries still favour a simple numerical formula.

With the basic provisions remaining deeply divided, the 37 states identified in the Chairman's draft text continues to be explored in the hope of some compromise. Three suggestions have been made to get around the problem of the treaty being held hostage:

1. a waiver provision, whereby even if one or more of the 37 states did not ratify within a given time-frame, those States which have ratified could bring the treaty into force anyway;

2. a provisional entry into force for those Parties who have ratified after a certain interval (necessary for the establishment of the IMS/IDC etc.);

3. a "positive conference" of the Parties, again after a period has elapsed after the treaty is opened for signature, which would discuss and decide on measures to help enable the treaty to enter into force (but without the possibility of amending the EIF provisions to allow the treaty to enter-into-force).

China and Russia strongly oppose a waiver provision, and the provisional entry into force has no gained much support. The third option appears to offer some hope for a compromise, but still leaves the problem of having the treaty's entry-into-force being blocked by one or more of the 37 states listed in the Chairman's draft.

5. Adoption of the CTBT


Support appears to be growing for a determined effort to conclude the CTBT by the end of June - something that appears now to be eminently achievable. China's speech also indicated its support for completion of the CTBT by the end of June (a position that had been stated previously outside of the formal negotiations).

With work on the composition of the Executive Council continuing to address details of the number and distribution of seats, the key outstanding problems appear to remain:
China's position on scope (incl. PNEs);
the division between the USA on the one-hand, and Pakistan, China and India on the other, on the triggering of an on- site inspection;
managed access and overflights;
entry-into-force.

This latter issue is the one where agreement seems furthest away.

Away from the Conference a number of events that could impact on the concluding weeks of work include: China's latest nuclear test - its 44th (and just one fewer than the United Kingdom) which has provoked protests around the world; whether or not the United States will proceed to conduct the first of its 'sub- critical experiments' and the vote of confidence in the new Indian government.
