Montenegrin Foreign Ministry accused the Russian Orthodox Church of interfering with the country's election process, adding the Church.
The Ministry's statement carried by the state broadcaster RTCG TV said that the Church's official for foreign relations Arch Bishop Ilarion said that Podgorica's ambassador to Russia "tried to assure him about the value" of the Law on Religious Freedom.
The Law has caused a bitter reaction from the Serbian Orthodox Church (SPC) and some violent protests in the tiny Adriatic republic.
Belgrade cautiously supported SPC in Montenegro which has the jurisdiction of the country's Orthodox Church since it is not autocephalous.
The Ministry's statement added the Montenegrin ambassador only informed the Russian Church's representatives "in a professional, diplomatic way," about the Law, as did all other Podgorica diplomats in different countries and the meetings with all other religious communities.
"Arch Bishop Ilarion is trying to impute the equal goals and methods by both Moscow and Belgrade patriarchies," the statement said.
It added such statements had always aimed to stop "Montenegro's foreign policy orientation towards Euro-Atlanticism and its wish to belong to the society of the Western liberal democracies."
