This decision highlights a mutual understanding to manage risks associated with AI in military applications responsibly. The agreement was achieved during the 31st APEC Economic Leaders' Meeting, with both leaders emphasizing the importance of stability in their relationship to prevent a new Cold War.

This is the first time such an agreement has been made, amidst a backdrop of previous tensions and strategic competition between the two nations. The agreement is seen as a step towards enhanced international cooperation on AI-related issues.
