We solve systematically for the right-handed quark mixings in the minimal left-right symmetric model which generally has both explicit and spontaneous $CP$ violations. The leading-order result has the same hierarchical structure as the left-handed Cabibbo-Kobayashi-Maskawa mixing, but with additional $CP$ phases originating from a spontaneous $CP$-violating phase in the Higgs vacuum expectation values. We explore the phenomenology entailed by the new right-handed mixing matrix, particularly the bounds on the mass of $W_R$ and the $CP$ phase of the Higgs vacuum expectation values.
