Iraq–Pakistan relations refers to the foreign relations between the Republic of Iraq and the Islamic Republic of Pakistan. Cultural interaction and economic trade between Indus Valley and Mesopotamia date back to 1800 BCE. In 1955 Iraq and Pakistan joined the Baghdad Pact, a military alliance against the Soviet Union. However, when the king of Iraq was assassinated in 1958, Iraq pulled out of the Baghdad Pact, which was renamed as the Central Treaty Organization (CENTO). Tensions persisted between Iraq and Pakistan through the late twentieth and early twenty-first centuries with the Iran–Iraq War, the Gulf War, and the Iraq War. However the relations stabilized. Pakistan currently maintains an embassy in Baghdad and Iraq in Islamabad.
