Dominican Republic–Haiti

The 395 km boundary between the Dominican Republic and Haiti, which divides the Caribbean island of Hispaniola, follows a combination of rivers, ridge lines, straight lines and roads. Hispaniola was roughly divided between Spain (the eastern two-thirds) and France (the western third) at the end of the 17th century, which was solidified in a general boundary agreement signed in 1777. The Dominican Republic and Haiti delimited the boundary in greater detail after independence in a 1929 Agreement, and approximately 80% of the boundary was subsequently demarcated. Disagreements over the demarcation of the remaining 20% of the border were settled in a 1935 Agreement and 1936 Protocol. In many areas the boundary is clearly visible on satellite imagery due to differing agricultural practices and significant deforestation on the Haitian side.
