So what is it about the so-called Mint countries that makes them so special? Why these four countries?
A friend who has followed the Bric story noted sardonically that they are probably "fresher" than the Brics. What they really share beyond having a lot of people, is that at least for the next 20 years, they have really good "inner" demographics - they are all going to see a rise in the number of people eligible to work relative to those not working.
This is the envy of many developed countries but also two of the Bric countries, China and Russia. So, if Mexico, Indonesia, Nigeria and Turkey get their act together, some of them could match Chinese-style double-digit rates between 2003 and 2008.
And as we all know, Turkey is in both the West and East. Nigeria is not really similar in this regard for now, partly because of Africa's lack of development, but it could be in the future if African countries stop fighting and trade with each other.
This might in fact be the basis for the Mint countries developing their own economic-political club just as the Bric countries did - one of the biggest surprises of the whole Bric thing for me. I can smell the possibility of a Mint club already.
In terms of wealth, Mexico and Turkey are at about the same level, earning annually about $10,000 (£6,100) per head. This compares with $3,500 (£2,100) per head in Indonesia and $1,500 (£900) per head in Nigeria, which is on a par with India. They are a bit behind Russia - $14,000 (£8,500) per head - and Brazil on $11,300 (£6,800), but still a bit ahead of China - $6,000 (£3,600).
I returned from my travels thinking it won't be so difficult for Nigeria and Turkey to positively surprise people, as many put far too much weight on the negative issues that are well-known - crime and corruption in Nigeria, for example, or heavy-handed government in Turkey.
Indonesia, I am less sure about. The country's challenges are as big as I thought and I didn't hear too many things that made me go "Wow" in terms of trying to deal with them. The country needs more of a sense of commercial purpose beyond commodities, and has to improve its infrastructure.
In Turkey, visits to white goods manufacturer Beko and Turkish Airlines, the world's fastest growing airline, definitely made me go "Wow", and in Nigeria, I was saying it all the time.
