Beijing is rewriting its wartime mobilization rules to let the state seize private property and tech resources outright — bad news for Taiwanese businesses operating in China and for private firms generally.

• The old law let the government borrow civilian resources in an emergency; the new one lets it take ownership permanently.
• Data, supply chains, and AI are now covered, so tech and industry fall under state control alongside factories and vehicles.
• Taiwanese companies in China face the risk that their assets get taken and their investment never comes back.
• The law now names "development interests" as something worth mobilizing for, and puts the whole system under Communist Party command.
• Taiwan security officials read the move as a sign of nervousness in Beijing rather than strength — turning every issue into a security issue.

Outlook: The rules kick in October 1, and companies with money tied up in China will be watching how aggressively they get used.
