If you thought OPEC had a grip on oil and oil prices wait till GPEC comes into play. The truth of the matter is that 3 countries control 90% of the worlds gas supplies and an alliance between them will be enough to bring the world to its knees.
The three countries that make up this exclusive club are Russia, Iran and Qatar and amongst them they have very strong ties, both in diplomatic and trade terms. Feel free to watch this news story made by Al Jazeera in 2008 and you will see why the Middle East has a such a strategic interest to the world, namely the West.
