"There are different views on the scope of the contribution. We therefore need some time for informal conversations to create a new platform to negotiate further," Norway's ambassador to the EU Atle Leikvoll, told Aftenposten.
"We are far apart," was all he would say on the size of the difference.
Prime Minister Erna Solberg recently complained that the EU has demanded "a significant amount" more than the 1.8 billion euros which EFTA countries Norway, Iceland and Liechtenstein have paid for access to the EU internal market over the past five years.
No new talks have yet been scheduled.
