Clicking on the link takes you to a beautifully made graph showing how the percentage of high technology exports from China, South Africa, Brazil and India have changed over the last 20 years. An indication of a countries ability to move up the manufacturing chain to more “value added” hi-tech goods. Unsurprisingly China demonstrated the biggest rise, although it has fallen slightly in recent years. India has very slowly increased its share of high technology exports , Brazil saw a big rise in the 1990s, followed by a big fall, while South Africa did not move much at all.
