In response to national security concerns and a series of reports highlighting the risks associated with employing Chinese engineers for Pentagon projects, Microsoft has decided to end its reliance on China-based teams for tech support of the U.S. military. This decision follows scrutiny from U.S. senators and external experts, who raised alarms about the potential exposure of sensitive defense information to espionage. The Pentagon is set to initiate a review of Microsoft’s past use of Chinese engineers, especially regarding their work on critical defense systems. Microsoft has emphasized that it will no longer utilize these engineers for Defense Department projects, marking a significant shift in its support policy aimed at safeguarding national security.
