The Arctic Security and Diplomacy Act is designed to bolster the United States' security and sovereignty in the Arctic, responding to increasing threats from foreign adversaries, particularly China and Russia. The legislation addresses concerns about territorial expansion, espionage, and military activities that could undermine U.S. interests in this strategically important region. Key provisions include a requirement for the Secretary of State, along with intelligence and homeland security officials, to develop a strategy within 180 days to combat espionage in the Arctic.
