Russia has made enough effort to substantiate its claim to the UN for a swathe of the Arctic shelf, Admiral Robert Papp, US Special Representative for the Arctic, told RIA Novosti.

He said that Russia is doing whatever is necessary to document its application, which shows that it will adhere to the United Nations Convention on the Law of the Sea.

According to Papp, Russia's bid could interfere with the interests of Canada and Denmark. Earlier Moscow held talks with Norway to avoid such discrepancies.

So far, Russia has been doing everything correctly, in accordance with the UN Convention on the Law of the Sea, Papp said.

Russian Minister of Natural Resources and Environment Sergei Donskoi said earlier that the decision on Russia's bid to expand its Arctic shelf limits will be taken by the UN commission regardless of disagreements with other counties that may also go after the same areas.

In early August, Russia submitted to the UN a revised application on expanding the limits of its continental shelf in the Arctic by including Lomonosov Ridge and other areas that are natural geological extensions of the Russian continental shelf.   

Since 2001, Russia has claimed the hydrocarbon-rich shelf area that includes Lomonosov Ridge and Mendeleev Ridge, but its bid was declined since it had not supplied sufficient evidence. It took over ten years to conduct new expeditions to the North Pole, as well as bathymetric surveys and seismic, geological and geophysical research in the Arctic Ocean to study the geological nature of the Lomonosov and Mendeleev ridges.
