The chapter traces a gradual convergence between the regulatory models that underpin these different domains of legal ordering one decade after the endorsement of the United Nations (UN) Guiding Principles on Business and Human Rights (UNGPs). It is argues that the location of business actors and activities within the state's territorial jurisdiction not only justifies domestic regulation with extraterritorial effect but also grounds international obligations to prevent and redress extraterritorial corporate human rights abuse. The chapter discusses doctrinal developments in international law galvanised by the Maastricht Principles on Extraterritorial Obligations of States in the Area of Economic, Social, and Cultural Rights that link states’ extraterritorial human rights obligations to authority, power, or control they may exercise over business actors and activities within their territorial jurisdiction. It discusses states’ increasing use of domestic law to impose legal due diligence requirements on these business actors and activities that reach out into the global supply/value chain.
