Question

what evidence suggests that the Indus people had trade relations with Mesopotamia

Answer 1

Mesopotamia's Imports from the Indus :

These included various types of timber, stone, and metal, as well as ivory and animals. Some of these were clearly of Indus origin; others were not products of the Indus region itself but were materials that the Harappans imported and traded on to Mesopotamia.

Answer 2

Answer:

The Indus Valley people had trade relations with Mesopotamia. The trade relationship during the later 3rd millennium was a direct one , ship from Meluhha 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 , people from Mesopotamia reached the Indus , so it is clear that the Harappans conducted the trade between two civilizations.
