The economy of the Mauryans was another big accomplishment. Under the Indo-Greek friendship treaty, international trade was thriving. The Silk Road provided a way to get their goods to other areas, and the Khyber Pass, located on the modern border of Pakistan and Afghanistan, developed into a strategically important place of trade and contact with the rest of the world. Through the Khyber Pass on the Silk Road the Mauryans could trade with Greece, Hellenic kingdoms, and the Malay Peninsula in West Asia. The main exports sent to those empires were silk, textiles, spices and exotic foods. Technology and science ideas were also exchanged with Europe and West Asia. Because of the peace and tranquility that the Mauryan dynasty was experiencing, internal trade within the empire flourished as well. The political unity allowed people from different areas of Mauryan India to travel and sell their merchandise at markets around their domain. The trade and economy of the Mauryan dynasty was one of their most influential achievements.
