In 2017, Iran's oil exports were spread among various countries, with China, India, European countries, and South Korea being key buyers. China led with 26%, followed by India at 20%, European countries at 19%, and South Korea at 12%. This diversification was crucial for Iran due to severe sanctions imposed on the country.

Fast forward to 2023, and the landscape has changed significantly. China's share has skyrocketed to 91%, with Syria at 7% and Venezuela at 2%. The remarkable shift in dynamics highlights China's dominant position in Iran's oil export market.
