Russia said on Wednesday that restrictions imposed by Norway were blocking goods for Russian-populated settlements on the Arctic archipelago of Svalbard, and threatened unspecified "retaliatory measures" unless Oslo resolves the issue.
Svalbard, midway between Norway's north coast and the North Pole, is part of Norway, but Russia has the right to exploit the archipelago's natural resources under a treaty signed in 1920, and some settlements there are populated mainly by Russians.
Norway, which is not in the EU but applies EU sanctions against Russia, has said sanctions would not affect the transport of goods by ship to Svalbard. But much of the freight for the archipelago's Russian settlements passes first through a checkpoint into mainland Norway, which is closed to sanctioned goods.
