Answer 1

They were two neighboring empires, both expanding and both wanting the same trade routes and the same ports. Especially Assyria sat on an important strategic position on many of those trade routes. Metal from Anatolia was an important item, for example.

Not to forget the rebelling states in the periphery like the Medes , who played one empire against the other.
