Mamsurov's rule in North Ossetia coincided with a deterioration of the relations with the neighboring republic of Ingushetia with which Ossetians fought a war over the Prigorodny district early in the 1990s. He has accused the Ingushetian authorities of deliberately stirring up the dispute between the two republics and waging an "information war" against North Ossetia. Mamsurov also supports closer cooperation with South Ossetia, Georgia's breakaway region which seeks integration with Russia though a union with North Ossetia. In July 2008, he accused the Western diplomats of plotting a "Jesuitical plan" of uniting South Ossetia and North Ossetia into a single entity in order to then push it into NATO through Georgia.
