South Korea convened an international summit on Monday seeking to establish a blueprint for the responsible use of artificial intelligence (AI) in the military, though any agreement is not expected to have binding powers to enforce it.

More than 90 countries including the United States and China have sent government representatives to the two-day summit in Seoul, which is the second such gathering.

The first summit was held in The Hague last year, where the United States, China and other nations endorsed a modest “call to action, opens new tab” without legal commitment.
