What was the farthest place the Harappans traded with?

For those who are not familiar with Harappa, this is a type of site that is located in Pakistan. Some people genuinely like going here because it looks like a small village. The village is quite modern and it matches well with the view that can be seen in this area. You may not be familiar with Mesopotamia too.

This area will not be called Mesopotamia for nothing. They have traded with Mesopotamians. Mesopotamia is known to be an area that is located on the Western side of Asia. Based on the location of Harappa and the location of Mesopotamia, it can be easy to see that they are far away from each other.
