The United States and Mexico have a close and complex bilateral relationship, with extensive economic linkages as neighbours and partners under the North American Free Trade Agreement (NAFTA). Bilateral relations are characterised by strong commercial and cultural ties and co-operation on a range of bilateral and international issues. In recent years, security issues have dominated the bilateral agenda, as the United States has supported Mexican President Felipe Calderon's campaign against drug trafficking organisations (DTOs) and organised crime. This book is an overview on the background, history, economic trends, and current issues facing Mexico today.
