A Joint Subcommittee of Delegates met in Lima, Peru, on August 7 and 8, 2025, to comply with the agreements reached in the Work Plan of the Second Extraordinary Meeting of the Chile-Peru Permanent Joint Boundary Commission.

The purpose of this meeting was to evaluate the possibility of densifying the markers between markers 10 and 11, as provided in the Minutes of the aforementioned Second Extraordinary Meeting.
The Joint Subcommittee of Delegates agreed on the technical need to carry out this densification in order to facilitate and enhance the visibility of the boundary layout on the ground. To this end, it proposed a working methodology that would meet the criteria of visibility, geodetic accuracy, and accessibility in accordance with the Regulations and Complementary Technical Standards. This proposed methodology will be submitted for approval at the next Ordinary Meeting and its implementation is estimated for the field work planned for March 2026.
