China and Japan AI Apps: Doubao, Kimi, DeepSeek, LINE — 2026-09-11
US security agencies have formally accused major Chinese AI developers, including DeepSeek and Moonshot AI (Kimi), of systematically siphoning proprietary models from American firms, escalating regulatory tensions. Meanwhile, in Japan, Rakuten’s latest survey reveals that nearly 40% of Gen Z users now utilize generative AI daily, signaling a rapid mainstream adoption shift.

US Accuses DeepSeek, Moonshot, and Alibaba of Model Siphoning
On September 9, 2026, US security agencies issued a detailed warning accusing Chinese AI companies, specifically naming DeepSeek, Moonshot AI (developer of Kimi), and Alibaba, of "systematically" extracting proprietary knowledge from American firms. The accusation alleges that these companies use malicious distillation techniques to copy capabilities from leading US models like ChatGPT and Claude. This development matters for the Daily desk as it threatens to disrupt the cross-border API usage and app-store availability of these popular consumer apps, potentially triggering new compliance requirements for developers integrating these models.
DeepSeek’s User Base and Web Traffic Surge
Despite the geopolitical friction, DeepSeek continues to demonstrate massive consumer traction. As of June 2026, DeepSeek recorded 129 million monthly app users in China. By August 2026, its web platform, deepseek.com, drew 353.8 million visits, representing approximately 6% of the traffic volume seen by ChatGPT’s website. This data highlights the resilience of Chinese consumer AI apps in domestic markets even amidst international scrutiny, with DeepSeek maintaining a strong position alongside ByteDance’s Doubao.
Alibaba’s QoderWake Targets Rival Ecosystems
Alibaba has launched "QoderWake," an AI tool that enables users to create "digital employees" or assistants that function within communication platforms owned by rivals, including ByteDance’s Feishu and Tencent’s WeCom. This strategic move allows Alibaba to penetrate competitors' enterprise and consumer workflows without requiring a full platform switch. For app store analysts, this represents a significant shift from closed ecosystems to interoperable AI agents, potentially altering how users engage with multiple AI apps simultaneously.
Local view
Japan: Gen Z Adopts AI for Daily Study
Local Japanese media outlets, including K-tai Watch and AI Watch, reported on a Rakuten survey published around September 6, 2026. The survey found that 38% of Gen Z respondents in Japan use generative AI tools "almost every day." The primary use case identified was "study and learning," indicating that consumer AI adoption in Japan is driven heavily by educational and productivity needs rather than just entertainment. This contrasts with some Western narratives that focus more on creative or coding applications.
China: Price Wars and Subscription Fatigue
Chinese consumer platforms like Smzdm (What's Worth Buying) are seeing high engagement on posts discussing the recent price hikes and subscription changes for AI services. Users are expressing frustration over DeepSeek’s August price increase and Kimi’s discontinuation of certain free tiers, with popular comments mocking previous promises of permanent low prices. This sentiment suggests that while user numbers remain high, consumer loyalty is becoming sensitive to pricing strategies as the initial "free trial" era ends.
Context & numbers
- DeepSeek Web Traffic: 353.8 million visits in August 2026 (~6% of ChatGPT's traffic volume).
- Japan Gen Z AI Usage: 38% of Gen Z in Japan use generative AI almost daily; top use case is studying.
- Doubao MAU: While specific September 2026 MAU figures were not in the immediate fresh results, earlier reports indicated Doubao maintained a lead with ~157 million MAU in late 2025, with continued dominance expected given ByteDance's integration of tools like TRAE and Coze into the Doubao ecosystem. (Note: Specific Sept 2026 MAU not explicitly updated in fresh sources, but context remains relevant)
On the radar
- Regulatory Fallout: Watch for potential app-store removals or restrictions in the US following the September 9 US government warnings against DeepSeek and Moonshot AI.
- ByteDance Integration: Continued rollout of "Doubao Work" features as ByteDance consolidates TRAE and Coze into the main Doubao app, aiming to compete directly with Tencent’s Yuanbao and Alibaba’s Qwen in the enterprise/consumer hybrid space.
