にとどまらずExtending beyond a boundary
Says that a range, effect, or fact does not stop at the named boundary but extends beyond it. It is especially useful for describing the spread of influence, damage, participation, relevance, or consequences.
How the sentence develops
The phrase before にとどまらず establishes a boundary. The following part then names an additional place, group, field, effect, or consequence beyond that boundary. The added range is often marked with も, though other wording is possible.
Typical kinds of expansion
The construction works best when the sentence presents a clear movement from a narrower range to a wider one.
