Botswana accounts for 6% of South Africa’s agricultural exports, valued at US$845 million in 2025, a trading relationship significant enough to warrant serious diplomatic attention. Yet the pattern of import bans that Botswana has imposed on South African fruits and vegetables since around 2021 continues to disrupt that relationship and the broader architecture of the Southern African Customs Union (SACU) is increasingly struggling to contain the tension.
The frustration is understandable on both sides. Botswana has legitimate ambitions to expand domestic food production and reduce its dependence on South African supply. A complete closure of the market at certain periods, imposed without a demonstrable national risk or disease threat amounts to protectionism within a customs union whose foundational logic is the opposite of protectionism. It disrupts South African farming communities, imposes cost burdens on Botswana’s own consumers and erodes the trust on which regional trade cooperation depends.
It seems the more constructive path would be collaboration rather than restriction. South Africa’s agribusiness sector, commodity associations, input suppliers and machinery companies have demonstrated through initiatives like the Citrus Growers Association’s cross-border technology sharing, that they can support agricultural development across the region rather than simply competing with it. Channelling that expertise and investment capacity into Botswana’s agricultural expansion ambitions would serve both countries better than recurring trade interruptions. The condition, however, must be a firm commitment from Botswana to fewer and less arbitrary market closures.
The Botswana-specific issue also points to a larger structural problem as SACU is becoming a constraint on South Africa’s ability to respond to the speed and complexity of modern trade negotiations. Where once the customs union’s collective bargaining model had clear advantages, today it creates opacity and unpredictability for potential trade partners who are primarily interested in South Africa rather than the wider bloc. Countries must be consulted, timelines extend and flexibility is lost. For a South African export economy under pressure in key markets including the US and actively seeking diversification, that constraint is increasingly costly. Pretoria needs the flexibility to move at its own pace whilst preserving the development programmes that provide genuine social support to neighbouring states, a difficult but necessary balance to strike. As South African leaders engage with Botswana’s government, these are conversations that can no longer be deferred.
