Seeding entrepreneurialism in emerging markets makes sense both altruistically and in return potential for an investor -- you're not competing in a saturated market, like say seed investing in the valley, and costs are low. If you can solve the other side, such as access to capital, M&A opportunity, and potentially international customers, as Jorn is doing, you're in a great place.
The part about training for business conduct feels a bit iffy in tone from the level of detail it goes into. I bought a company in Germany a few years back, and my Canadian sensibilities certainly offended folks until I learned the rules of the local culture. Any cross border business interactions are fraught with this.
A few of my friends are currently investing/managing a company out of Ghana. Extremely low investment has yielded a great growth curve, and they're changing how sub-Saharan Africans manage their finances. They're some of the happiest investor/entrepreneurs I know.
