This article seeks to explain South Africa's ostensible emergence as a
middle power. It makes the case for the use of a Coxian-based critica
l theory perspective, which relates the interrelationship between chan
ge at the level of world order, the nature of production and the socia
l forces operative in the middle power's state-societal complex to exp
lain South Africa's increasingly active role in international affairs.
Playing a mediatory role helps the South African state make diverse f
oreign policy goals more compatible and it also goes some way in thwar
ting criticism levelled at its foreign policy in the state-societal do
main. Contrary to earlier theorising about middle powers, this article
supports a more recent contention that middle powers act in their own
(ie dominant societal) interests. The value of such a perspective is
illustrated in the light of current debates about the apparent incongr
uity of South African foreign policy.
