More than 90 nations, including the U.S. and China, will convene at a two-day summit in Seoul starting Monday to attempt to establish a blueprint for the use of AI in the military.

As Reuters reports, participants hope to establish minimum guardrails and suggest principles for “responsible” AI deployment aligned with NATO principles.

The summit is the second such event of its kind, following a gathering in Amsterdam in 2023 where countries committed to a “call to action” on military AI use. The topic has taken on new urgency as nations like Ukraine show an eagerness to adopt AI-powered drones and other autonomous weaponry.

Some countries have shown a willingness to consider international limits on AI that could do harm. Last week, the U.S., Britain and the EU signed the world’s first international AI treaty, which focuses on the defense of human rights of people affected by AI.
