"While virtually no object of clearly West Asiatic origin has been discovered in the Greater Indus Valley, dozens of seals bearing the Indus script have been found in Mesopotamia and the Persian Gulf, along with Harappan weights and jewelry. Cuneiform texts also speak of sea trade with foreign countries, and there is nowadays wide agreement that the most distant of these countries, Meluhha, was the Greater Indus Valley."
