AI demand keeps Microsoft in China despite 15 office closures

For AI infrastructure teams, the most important line in the report is not the 15 closed offices, but that Microsoft stays because Chinese companies like ByteDance need Western technology to manage overseas AI operations. That dependency, not domestic Chinese demand, is now the core of Microsoft's AI window in the country.

Microsoft's retreat from China, once unthinkable, has become a defining strategic puzzle of the US-China technology decoupling. According to reporting citing five company sources and corporate filings, at least 15 Microsoft branch offices and joint ventures in China have been shuttered over the past five years, and in 2023 the company internally considered exiting the market entirely. The fact that Microsoft chose to stay, with no current plans to leave, reflects a calculated bet that a slim but profitable window remains open—largely because the global AI boom has made Chinese technology companies dependent on Western infrastructure.

Bill Gates and then-CEO Steve Ballmer suggested Google was overreacting.

The reversal is striking against history. In 2010, when Google exited China over censorship and cyberattacks, Microsoft's leadership publicly criticized the move. Bill Gates and then-CEO Steve Ballmer suggested Google was overreacting. The China business Microsoft once defended has since dwindled to a marginal contributor: China accounted for just 1.5% of Microsoft's global revenue in 2024. That collapse has been driven by two forces. Since 2017, Beijing has pushed domestic software, viewing it as more secure and increasingly competitive with Windows and Office. At the same time, US export controls on advanced technology have made it difficult for Microsoft to scale its most lucrative AI and cloud services inside China, capping the upside of a market it once considered core to global growth.

Yet the retreat is not an exit. Microsoft ultimately decided to remain because it had carved out a profitable business servicing Chinese companies like TikTok owner ByteDance, which need Western technology to manage overseas operations. This is a crucial distinction: the value of Microsoft's China presence is no longer primarily serving the domestic Chinese market, but enabling Chinese firms to operate globally. Three people familiar with the matter said Microsoft believed it needed a presence to serve these clients and stay close to their evolving technology needs. That logic ties Microsoft's China strategy directly to the AI boom, as Chinese tech companies expand internationally and require cloud, software, and AI infrastructure that is both globally interoperable and compliant with foreign regulations.
