In part 4 of our month-long conversation about the role business can and should play in the world's peace processes, Donald L. Cassell, Jr. draws from his many years advocating for his home country of Liberia to discuss how culture plays a central role to the development of economic opportunity and stability.

By developing their employees, business holds a unique and important ability to impact the peace-building process.
