China will tighten oversight of its push into advanced technology, seeking to curb investment bubbles while ensuring artificial intelligence remains 'safe, reliable and controllable,' according to policy guidelines issued Friday by the ruling Communist Party and the cabinet.

As Beijing ramps up support for high-tech manufacturing and strategic industries to boost technological self-sufficiency amid rivalry with the United States, the guidelines warned against blind investment and excessive expansion into emerging sectors. Officials were told to prioritize the real economy and avoid industrial hollowing-out.

The document calls for breakthroughs in AI theory and core technologies, stronger supplies of computing power, algorithms and data, and national pilot bases for industrial AI applications. It fully implements the 'AI Plus' initiative, using AI to upgrade traditional industries and accelerate intelligent products including connected new-energy vehicles, AI-enabled phones and computers, and humanoid robots.

The guidelines also pledge technology monitoring, risk-warning and emergency-response systems for AI, and invoke President Xi Jinping's 'new productive forces' doctrine - introduced in 2023 - emphasizing scientific breakthroughs and industrial upgrading across China's manufacturing base.
