The last in our list, Group H is particularly rich and varied, including a sprawling super power in Russia, a quaint and inviting Belgium, luxury-loving South Korea and one of Africa's most stable economies in Algeria .
Historically, Belgium acted as distributor and middleman to many commodities reaching Europe from overseas, such as cotton and wool. And in many ways, it retains that role to the present day. Belgium is a developed and well-established economy, driven by its private industry and tertiary sectors.
And with Brussels acting as the home city of both the EU and NATO, there is a wealthy and diverse hospitality industry which stretches out beyond the capital.
Despite long-term sluggish growth, there are many attractive facets of Belgian society that would appeal to an outside investor: from its social stability to the diversity of its bilingual, multicultural identity, and affluent population. Beyond the obvious appeal of high-end hospitality, Belgium is an ideal hub for business to business services and trade relations advisers.
Africa's largest country in geographic terms, Algeria offers a diverse and stable mixed economy with many natural assets. From its long Mediterranean coastline to its petrochemical industry and oil reserves, Algeria's domestic economy may be driven by its large public sector, but its wealth derives from exports.
Commentators have long held Algeria up as an under-performing economy considering the relatively resource-rich nature of the country. Its large agricultural base operates on a subsistence level, yet does not meet the consumption of the population; its fisheries industry is lacking infrastructure, and its financial sector is dominated by the need to fund low-yielding projects in the public sector.
So look to Algeria's expansive coastline for sound investment opportunities: from fishing to support services for the industry like processing and delivery. It may be that the country's banks are queuing up to help with the finance!
The Russian economy remains a mixed picture of both robustness and personal poverty. Rich in oil and gas, which it sells in massive quantities to the EU and China, Russia is nevertheless a victim of stagnation and mass unemployment, and remains at the mercy of fluctuations in the fossil fuel markets. With limits on banking, trade and press freedoms, Russia is one territory that has long been difficult to break into.
With its well-known social inequality and its cadre of super-rich oligarchs, Russia is a prime marketplace for luxury goods: seen as a wealth-storing asset that hedges against global currency movements. Because of this, fine art brokers are always welcome in Russia. A more conscientious investor may find a public calling for financial and press freedoms makes fertile ground for internet and bitcoin services.
Consistently one of the world's top twenty territories, South Korea has benefited massively from its outward looking society, whilst its neighbour to the north has stagnated under its totalitarian governments. Today, South Korea is one of the continent's most open and free trading zones, with a fully modernised economy powered by a large scale industrial and manufacturing base.
South Korea recovered rapidly from the Asian financial crisis of 1997 and the 2008 credit crunch, thanks to domestic consumption. And, with manufacturing driven by high-end technology sold to China and the US, the Korean society has become increasingly aspirational and now works to own the items it once sold to the world.
Equally, there is prestige in foreign-made luxury goods. So maybe ambitious Korea might be the perfect location for that classic American car dealership you always dreamed of owning!
