“In response to concerns raised earlier this week about US-supervised foreign engineers, Microsoft has made changes to our support for US Government customers to assure that no China-based engineering teams are providing technical assistance for DoD Government cloud and related services,” the company’s chief communications officer, Frank Shaw, announced on X Friday afternoon.

Microsoft’s announcement came hours after Defense Secretary Pete Hegseth said his agency would look into Microsoft’s use of foreign-based engineers to help maintain the highly sensitive cloud systems.

“Foreign engineers — from any country, including of course China — should NEVER be allowed to maintain or access DoD systems,” Hegseth wrote in a post on X Friday.
