I totally agree with Antony Oliver and RedR regarding the benefit of overseas work experience. From my own experience overseas work is a vital part of the development of an engineer.
How much more valuable therefore to provide opportunities for engineers from low and middle-income countries to be able to experience their own version of this by being invited to work in this country for a while.
We are also missing a trick if we do not, as an industry and an institution, make this a possibility. Perhaps a slogan I learnt from oil-industry colleagues - 'one in, one out' - should be our motto for aid and development in our globalising world. Capacity-building cannot just be one way.
