"They have not just regional but global responsibilities, Russia does. And so far we are not seeing what they are doing as not in keeping with their global strategic responsibilities… Thus far, we are not seeing their activities destabilizing the region," Kirby said on the sidelines of the Conference on Global Leadership in the Arctic in Anchorage, Alaska on Monday.
Kirby stressed, however, that the United States stays "vigilant."
"We certainly are watching what Russia is doing in the region, there is no question about that," he said.
Kirby emphasized that the United States consistently discusses the Arctic issues with Russia, including its concerns over Russia's activities there.
Russia has been pressing ahead with efforts to develop its Arctic territories, including hydrocarbon production and the development of the Northern Sea Route, which is gaining importance as an alternative to traditional routes from Europe to Asia. The country has also boosted its military presence in the area.
Russian President Vladimir Putin has previously stated that Russia does not plan to militarize the Arctic, but will take the necessary steps to ensure its defense capabilities in the region.
