Under the leadership of the governing African National Congress, the South African government has long touted the idea of becoming a developmental state as the country's ultimate response to rising unemployment, poverty and inequality. This idea aligns with the rapid economic growth and industrialization experienced by the East Asian developmental states through directing the state's administrative capacities, resources and policies towards attaining national developmental goals.Similarly, the National Development Plan pins South Africa's developmental state ambition on creating a capable developmental state and the formation of dynamic institutions capable of utilizing the state's administrative powers, resources and policies to pursue developmental goals. However, the country's state institutions, administrative capacities and resources have been challenged by the state capture debacle that shed light on the corrupt relationship between the political elite and the business elite.
