就 (jiù) can be used to limit the scope of a comment, used in the following structure:

Basic Structure

就 + topic + 来说/而言 + comment

This emphasizes that the speaker is just commenting on that particular topic and nothing else, like "just with regards to" in English. In this sense it is similar to 至于, but is generally used to introduce a new idea, rather than to move on from a previous related topic.
