China's revised law on national defence mobilisation takes effect on 1 October, expanding the state's powers to call up resources in case of conflict.

The changes update rules on how the government can mobilise people, companies and materials during wartime or national emergencies. Analysts say the law widens the scope of what can be requisitioned.

The timing has drawn attention across the region. Neighbouring countries are watching how Beijing frames the law and whether it signals a tougher security posture. coming amid tensions over Taiwan and the South China Sea.

Chinese officials have described the changes as routine legal updates. But military analysts say the law gives Beijing more tools to prepare the economy and society for a crisis. Regional capitals are expected to seek clarity from Beijing.

The law also covers the mobilisation of transport, communication and cyber resources. Legal experts say companies operating in China should study the new compliance duties.
