In March 2000, Belize and Guatemala resumed discussions on their territorial dispute with the assistance of the Organization of American States (OAS) Secretary General. On November 8, 2000, they signed the first Agreement on Confidence Building Measures, establishing an "Adjacency Line" and a one-kilometer "Adjacency Zone" on either side. A second Agreement was signed on February 7, 2003, and subsequently amended in September 2005 by the "Agreement on a Framework for Negotiation and Confidence Building Measures between Belize and Guatemala". The central point of this Agreement, which is still in force, was on the one hand, that the Secretary General should appoint, at his discretion, a high-ranking official as his Special Representative (SRSG), and on the other hand, the establishment of the OAS Office in the Adjacency Zone (OAS/AZ).
