Daniel Sánchez Bustamante Vásquez (10 April 1871 – 5 August 1933)[1] was a Bolivian educator, politician, lawyer, professor, author, and diplomat.

[1] In 1901, he was named vice secretary of the Office of the Ministry of Government and, as such, was in charge of the drafting of the Electoral and Printing Regulations.

During previous negotiations, both parties accepted the arbitration of Argentine President José Figueroa Alcorta, agreeing on making modifications.

[6] Sánchez Bustamante also endorsed a treaty of Commerce and River Navigation between Bolivia and Brazil, signed in Rio de Janeiro on 12 August 1910.

[1] After 1910, shortly before he left his ministerial position, an incident on the Peruvian border took place which threatened the renewal of hostilities between Bolivia and Peru.

The smaller Peruvian garrison which defended said post was exterminated; among the casualties of the border skirmish were lieutenant Alejandro Acevedo and sergeant Carlos Zela (19 November 1910).

However, the matter was not escalated, since a protocol signed in 1911 between both countries smoothed out the dispute surrounding the execution of the boundary treaty.

[1] During the Chaco War between Bolivia and Paraguay, he was sent to Buenos Aires as advisor to the Bolivian commission in the peace negotiations, and even met with Argentine President José Félix Uriburu.

[9] One of his grandsons, son of his daughter Carmen, is Gonzalo Sánchez de Lozada, who was President of Bolivia on two occasions, (1993-1997) and (2002–2003).
