Why Chinese Linux OSes Struggled and What’s Driving Their New Era

Early Beginnings of Domestic Operating Systems

China began developing its own operating systems in the 1970s, importing UNIX in 1979 and later joining the global Linux wave in the late 1990s. Early Linux‑based releases such as Red Flag, Xteam, and Blue Point appeared alongside later variants like NeoKylin, Deepin, and UnionTech.

Rise and Fall of Early Distributions

Red Flag Linux launched in 1999, achieved profitability in 2005, but suffered a funding crisis and was liquidated in 2014 before being revived by a new owner. Blue Point quickly rose to a leading OEM supplier and listed on NASDAQ in 2000, only to collapse after the dot‑com bust. Turbolinux (later TuoLinSi) entered China in 1999, peaked between 2000‑2006, and withdrew after market contraction. Xteam Linux enjoyed a brief dominance after its 1999 release but ceased updates after 2003.

Four Core Weaknesses of the Early Industry

Immature hardware and software ecosystem – domestic CPUs lagged behind Intel and applications lacked compatibility.

Insufficient marketization – many projects were research‑institution driven, lacking professional product management and support.

Low innovation and high homogeneity – products were rushed to market without sustained differentiation.

Fragmented landscape – numerous small‑scale OS versions prevented economies of scale.

New Era: Ecosystem Maturation Since 2015

Starting in 2015, China’s IT sector entered a “usable” stage driven by coordinated technology, economic, and policy environments, including the 2006 “Nuclear‑High‑End‑Base” (核高基) project that funded domestic CPUs, OS kernels, and software platforms.

Key Domestic CPUs

Loongson : MIPS‑based, launched 3A/B3000 series in 2016 (SPEC 10‑11), later 3A/B4000 and 7A2000 reaching SPEC 20‑30.

Phytium : Initially SPARC, switched to ARM; FT‑1500A (2014) matched Intel Xeon E3, FT‑2000+ (2017) and FT2000/4 (2019) improved performance.

Huawei Kunpeng : 920 series (2019) based on ARM v8.2, 7 nm process, integrated into the broader “Xinchuang” ecosystem.

UOS and the Six Unifications

UnionTech’s UOS, released in January 2020, targets four architectures (AMD64, ARM64, MIPS64, SW64) and supports major domestic CPUs. Its strategy is built on six unifications:

Unified version – a single code base builds for all architectures.

Unified development platform – common toolchains and community support.

Unified app store – signed, secure distribution channel.

Unified ABI/API – one‑time development runs on multiple CPUs.

Unified standards – consistent testing and certification.

Unified documentation – coherent developer, maintenance, and user guides.

These unifications simplify cross‑platform adaptation, reduce development cost, and accelerate ecosystem growth.

Industry Consolidation and Leading Players

Only a few vendors have survived: NeoKylin, Galaxy Kylin, Deepin, and UnionTech. Deepin’s desktop environment (DDE) and its partnership with Huawei have boosted visibility. UnionTech’s UOS has attracted over 2,000 partners and is positioned to replace Windows in many office scenarios.

Major Software Vendors and Their Strategies

China Software (Zhongbiao) merged with Tianjin Kylin to form Kylin Software, offering the Galaxy Kylin desktop, cloud, and cluster products, plus high‑availability and load‑balancing solutions built on domestic CPUs. Their ecosystem integrates hardware, middleware, and applications across government, finance, education, and defense.

Overall, the Chinese operating‑system market is shifting from a fragmented, hardware‑constrained landscape to a more unified, policy‑supported ecosystem where a handful of well‑funded companies drive standards, security, and cross‑platform compatibility.
