REYKJAVIK, Iceland — Sen. Angus King continued his push for the U.S. to play an increased leadership role in the Arctic.

King spoke Sunday at a plenary session of the 2015 Arctic Circle Assembly in Iceland.

The independent from Maine said the rapidly changing Arctic environment presents challenges, but also opportunities.

“Inherent in those challenges are also opportunities – opportunities for nations to work together to cultivate prosperity and expand educational and cultural exchanges that could define the future of the Arctic,” King said, according to a statement put out by his staff.

Also participating in Sunday’s session were U.S. Navy and State Department officials.

King is a co-founding member of the Senate Arctic Caucus. He arrived in Iceland on Friday along with a delegation from Maine that includes local and state officials, business leaders, researchers, educators and trade experts.

The Arctic Circle Assembly, which attracts more than 1,500 participants from nearly 50 countries, is held each October at the Harpa Conference Center and Conference Hall in Reykjavik.
