(Bloomberg) — Alibaba Group Holding Ltd. will invest 200 billion yuan ($28 billion) on cloud infrastructure such as datacenters over the next three years, a major effort to extend one of its fastest-growing business segments to more countries.

The Chinese e-commerce giant plans to build more datacenters to complement an existing network covering 21 regions around the world, the company said in a statement. It will continue to develop its own technologies in areas such as AI-inference chips to support that expansion in cloud services, it added.

Cloud computing has been one of the fastest-growing initiatives for Alibaba as it expands beyond its traditional e-commerce focus. The sector’s revenue rose 62% to 10.7 billion yuan in the December quarter, driven by contributions from the company’s public cloud and hybrid cloud operations.

Alibaba warned in February that the coronavirus outbreak would have a broad impact on the Chinese economy and its business. While certain operations like grocery delivery and online entertainment benefited, others were hurt by complications with delivery and quarantine.
