  Recently, the leading soft gluon theorem with single soft emission was shown
to be the Ward identity of a two dimensional $\cal G$-Kac-Moody symmetry. In
this note, 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 sub-leading soft gluon theorem can follow from the same
symmetry.
