World oil price ranking
It can be seen from the data that the country with the cheapest oil price is Venezuela, with an average oil price of only US$0.01/litre. The second-ranking country is Iran, a major oil country in the Middle East. The huge fuel subsidy has become a past tense in Iran. At present, the price of gasoline in Iran is 0.29 US dollars per liter, which is equivalent to 1.99 yuan. Although oil prices are much higher than Venezuela, they are cheaper than supermarket water.
