China tightens grip on overseas travel with sweeping new law

China has passed a broad new law to tighten control over overseas travel. President Xi Jinping is leading the effort to protect state secrets, advanced technology, and highly skilled workers. The law gives the government stronger power to decide who may leave the country and under what conditions. It reflects Beijing's growing focus on keeping sensitive information and key talent inside China. Officials say the measure is needed for national security. Critics argue it could limit personal freedom and slow international exchange. The full impact of the law will become clear as it is put into practice.
