  In this note, following \cite{Chitescuetal2014}, we show that the
Monge-Kantorovich norm on the vector space of countably additive measures on a
compact metric space has a primal representation analogous to the Hanin norm,
meaning that similarly to the Hanin norm, the Monge-Kantorovich norm can be
seen as an extension of the Kantorovich-Rubinstein norm from the vector
subspace of zero-charge measures, implying a number of novel results, such as
the equivalence of the Monge-Kantorovich and Hanin norms.
