One of the more elaborated news on that topic:

Chinese officials have implicitly acknowledged responsibility for a series of sophisticated cyber intrusions targeting critical U.S. infrastructure.

During a high-level meeting in Geneva with American officials, representatives from China’s Ministry of Foreign Affairs indirectly linked years of computer network breaches at U.S. ports, water utilities, airports, and other critical targets to increasing U.S. policy support for Taiwan [...]

Wang Lei, a top cyber official with China’s Ministry of Foreign Affairs, made the comments after U.S. representatives emphasized that China appeared not to understand how dangerous prepositioning in civilian critical infrastructure was, and how such actions could be viewed as an act of war [...]

The admission is considered extraordinary, as Chinese officials have typically denied involvement in cyber operations, blamed criminal entities, or accused the U.S. of fabricating allegations.

Dakota Cary, a China expert at cybersecurity firm SentinelOne, noted that such an acknowledgment, even indirectly, likely required instructions from the highest levels of President Xi Jinping’s government.
