The Harappas had commercial relations with __________

The trade relationship during the later 3rd millennium was a direct one: ships from Meluhha (the Indus) docked in Mesopotamian ports; some Meluhhans settled in Sumer; and there is a seal belonging to a Mesopotamian whose job it was to act as an interpreter of the Meluhhan language. On the other hand, there is nothing to suggest that people from Mesopotamia reached the Indus, so it is clear that the Harappans conducted the trade between the two civilizations. Mesopotamian ships sailed the length of the Gulf, as far as the western coast of Magan (Oman peninsula), trading directly with Magan and with Dilmun (Bahrain); ships from Magan and Dilmun also docked in Mesopotamian ports.
