South Africa has been developing chemical weapons since the beginning of World War I. The development of such weapons was South Africas response to the increasing threat of chemical and biological weapons (CBW) use from other countries. The establishment of the 1925 Geneva Convention, which banned the use of such weapons in warfare, temporarily decreased tensions concerning the threat. However, South Africa did not entirely cease production and research of CBW following the Geneva Convention. In fact, during World War II, South Africa sidestepped the convention protocol and began planning a more extensive CBW program, to protect the country from the threat of the Nazi regime.
Following the war, the South African Defense Force (SADF) continued with CBW research and development, but on a much smaller scale. Much of the CBW produced during that time was tear gas, CX powder and mustard gas. The non-lethal agents were utilized mostly to control crowds.
It was not until the 1970s that South Africas CBW program began stepping up production of more destructive agents, despite the ratification of the Convention on the Prohibition of the Development, Production and Stockpiling of Bacteriological and Toxin Weapons and on their Destruction (BTWC) in 1975. The reasoning behind the increased production of more aggressive biological and chemical agents was to prevent a total Communist onslaught from the Soviet Union and Cuban-backed regimes, which threatened a complete takeover of Mozambique and Angola during the mid to late 1970s. It was believed that the Cuban troops deployed in those regions at the time had chemical weapons, which the South African government feared they would use.

Much like South Africas right-wing apartheid regime, the crimes committed by the ANC were vast and brutal. Many civilians and government officials were ruthlessly murdered in the name of liberation. ANC soldiers who refused to fight were physically and psychologically tortured and murdered in death camps located in Angola. The ANCs primary goal was to wage a campaign against the white-led regime that threatened to suppress them at any means.

Such tensions were believed to have also led to the use of CBW by the SADF and the continued enhancement and extension of the ongoing CBW program. According to Gould and Folbs article, The South African Chemical and Biological Warfare Program: An Overview, South Africas Prime Minister P.W. Botha called on the countrys security forces to devise a more efficient method in which to deal with internal, as well as external conflicts. The SADFs response to Bothas request was the implementation of a new and highly secretive CBW program in April 1981, code-named Project Coast.

Basson learned that the CBW programs in Western Europe were not defensive, but rather offensive in nature, which caused concern for the South African government. In order to keep pace with other western countries, the SADF put plans for Project Coast in full gear. Basson became the project officer of Project Coast and was given the task of bringing South Africas CBW program up to date.
The aim of the new program was primarily to conduct highly secretive research into the various aspects of CBW warfare, including offensive and defensive capabilities. Moreover, the program aimed to develop CBW, as well as provide conventional and covert support of CBW production, technology and industrial operations. In short, Project Coast included the research and production of offensive and defensive CBW weapons, which explicitly violated the BTWC agreement.
According to a paper by Burgess and Purkitt, The Rollback of South Africas Chemical and Biological Warfare Program, Basson managed all aspects of Project Coast. His duties included the recruitment of approximately 200 medical and scientific researchers from around the world, management of annual funds of $10 million and the establishment and supervision of the program and related companies. Bassons activities remained largely unsupervised because those people above him in the chain of command lacked the scientific experience and knowledge essential for the operation and management of the project.
