South Africa–European Union relations Wikipedia
Since the end of South Africa's apartheid, EU South African relations have flourished and they began a "Strategic Partnership" in 2007. In 1999 the two sides signed a Trade, Development and Cooperation Agreement (TDCA) which entered into force in 2004, with some provisions being applied from 2000. The TDCA covered a wide range of issues from political cooperation, development and the establishment of a free trade area (FTA). The liberalisation schedules were completed by 2012. Since the signing of the Agreement, trade in goods between the two partners has increased by more than 120%, and foreign direct investment has grown five-fold.
South Africa is the EU's largest trading partner in Southern Africa and has a FTA with the EU. South Africa's main exports to the EU are fuels and mining products (27%), machinery and transport equipment (18%) and other semi-manufactured goods (16%). However they are growing and becoming more diverse. European exports to South Africa are primarily machinery & transport equipment (50%), chemicals (15%) and other semi-machinery (10%).
