The cost of shipping a standard 40-foot container has tripled since 2000 and labour cost increases have risen by average of 19% per year in China compared with just 3% in the US.

And, of course, you need some reliable forecasts of where the economics of offshoring versus onshoring are heading - including predictions on crude-oil prices.
