Tehran (Iran) is one of the Middle East's largest economies with a young population, with key industries in oil and gas, petrochemicals, automotive, and agriculture. Baku (Azerbaijan) is a Caspian energy hub connecting Europe and Central Asia, known for oil and gas, petrochemicals, agriculture, and tourism.
