Abstract
Recently, the leading soft gluon theorem with single soft emission was shown to be the Ward identity of a two-dimensional -Kac-Moody symmetry. In this paper, we show that the leading soft gluon theorem can be interpreted as the Ward identity for the asymptotic symmetries of non-Abelian gauge theory. We further argue that the subleading soft gluon theorem can follow from the same symmetry.
