10. Oman
Total score – 27
Back in 2014, the World Bank states that the oil rents were 28% of the country’s GDP, down from nearly half back in the 1970s. This, as you will see from here on out, is a difference that you’ll notice in few countries, since for most of the nations on our list, the importance of the oil rents have risen in the past decades, not dropped.
At the same time, back in 2013, Oman’s fuel exports were 82.5% of the country’s merchandise exports, making oil a rather important part of the country’s economy. In fact, oil production and refining, alongside natural and liquefied natural gas production are the two main industries in the country, followed by construction. Its main export partners are China, Japan and the United Arab Emirates, although the numbers may vary.
