Norway will close its ports and borders to Russian goods traffic, said the local media on Friday.
The decision was taken in line with the latest EU sanctions, Foreign Minister Anniken Huitfeldt told public broadcaster NRK.
The closure of the seaports takes effect on May 7, while the border closed on Friday, according to NRK.
NRK said fishing vessels will be exempted from the decision unless they are owned by individuals who are subjected to sanctions.
Huitfeldt stressed that Svalbard Archipelago in the Arctic Sea will also not be included in the sanctions in line with the 1925 Svalbard Treaty.
Norway does not expect a reaction from Russia, he added.
