币界网报道：NATO members have agreed to increase their minimum defense spending commitment from 2% to 5% of GDP, marking a significant shift in the alliance's economic strategy amid rising geopolitical tensions. The decision, reached during an emergency meeting, comes as NATO seeks to bolster collective security following Russia's invasion of Ukraine and growing concerns about China's military expansion. While the move has drawn criticism from some member states facing economic challenges, proponents argue the higher threshold is necessary to modernize defenses and maintain technological superiority. The increased funding is expected to accelerate development of emerging technologies including AI, quantum computing, and blockchain applications for defense systems. NATO Secretary General emphasized this commitment ensures the alliance remains "future-proof" against evolving threats. The policy change will be implemented gradually, with member states given until 2030 to meet the new target.
