H.M.S. Reid sends instructions to the UK Embassy in Pretoria in preparation for a meeting with South African Secretary for Foreign Affairs Brand Fourie. Reid informs them that the Prime Minister wishes to send his concerns about the possibility of South Africa exploding a nuclear device.

Nye stated that at present the United States preferred to "concentrate on pressing South Africa to adhere to the NPT rather than continuing to enquire about the nature of the Kalahari facility." The State Department assessment was that while South Africa was capable of building a bomb at short notice, they did not actually plan to test one at this time.

Mallaby reports on a conversation at the Nuclear Suppliers Meeting with the US Deputy Under-Secretary for Security Assistance, Nye, on whether the US would raise the issue of South Africa's Kalahari nuclear testing facility. The US assumption was that the South Africans intended to "be on the brink of having a nuclear weapons capability" in order to "moderate Western diplomatic pressure on her about racial and other issues."

Mallaby outlines the UK position on South African accession to the Non-Proliferation Treaty.
