This chapter addresses the issue of how a treaty focused on corporations and human rights might evolve, through continued advocacy and State practice. It also examines why it is more likely that a series of narrower treaties will emerge, focused on specific ways States might regulate corporations as a means of preventing harm. As a point of comparison, the article examines the anti-corruption movement - which began with a US law prohibiting foreign bribery and led to the 2005 United Nations Convention Against Corruption (UNCAC).
