For enterprises expanding overseas, the issue is no longer confined to the laws of a single country; mere compliance with the host country's labor laws is far from sufficient. Global regulation is facing formidable challenges—including the hardening of "soft law," the expansion of extraterritorial jurisdiction, mandatory human rights due diligence, and accountability across the entire supply chain. These are compounded by a complex web of constraints: Chinese legal requirements, host country laws, international labor standards, ESG mandates, client codes of conduct, trade agreements, and imperatives regarding national and supply chain security. Consequently, labor-related risks are highly intricate, easily triggering legal crises, operational paralysis, and severe damage to brand reputation. Establishing a "three-in-one" cross-border labor compliance framework—integrating domestic, international, and transnational labor laws—and adhering to the principle of "dual compliance" not only ensures the steady, long-term success of corporate globalization but also effectively advances global goals for decent work, social justice, and sustainable development.
