Note again that the exchange rate gets a mention - low wages as previously mentioned are not the sole driver of China's growth in exports and manufacturing production.

Just How Low are China's Labour Costs? by Janet Ceglowski and Stephen Golub
This paper provides a new perspective on Chinese international competitiveness in manufacturing using relative unit labour costs. We find that Chinese unit labour costs are about 25–40 per cent of US labour costs. They are also low relative to costs in the EU, Japan, Mexico, Korea and most other newly industrialising countries. However, China's relative unit labour costs indicate a substantially smaller cost advantage than that implied by a comparison of wages alone. China's cost advantage derives from large currency devaluations that preceded the establishment of a de facto peg around 1995, and rapid productivity growth in the period since 1995.
