La Paz, Sept. 17 (SANA)BoliviaandParaguayhave completed the demarcation of their shared border, ending an 88-year process that followed a peace treaty signed after theChaco War, AFP reported Thursday.

Bolivia’s Foreign Ministry said the two countries completed the work after three days of meetings in La Paz, concluding a process carried out by technical commissions from both sides.

“The completion of the border demarcation strengthens a bilateral relationship based on trust and cooperation between the two countries and closes a historic chapter by establishing a secure and mutually recognized border,” the ministry said.

Paraguay’s Foreign Ministry said the completion would make Bolivia and Paraguay the only two countries in South America to share a “fully demarcated border.”

The Bolivia-Paraguay Joint Border Demarcation Commission used high-precision drone surveys and government records to determine the final unresolved 3.5-kilometer (2.2-mile) section along the Rio Negro.

Bolivia and Paraguay fought the Chaco War from 1932 to 1935 over control of the Chaco Boreal region. The two countries signed a peace treaty in 1938, beginning the decades-long process of demarcating their roughly 755-kilometer (469-mile) border.
