Practice Relating to Rule 83. Removal or Neutralization of Landmines
Sweden’s IHL Manual (1991) states:
According to Protocol II [to the 1980 Convention on Certain Conventional Weapons], the parties to a conflict shall record the locations of all pre-planned minefields … The parties shall retain all mine records and, after cessation of hostilities, shall make them available to the adversary – this provision, however, is not obligatory in a case where the latter party still has combat forces on the wrong side of the frontier. 
Sweden, International Humanitarian Law in Armed Conflict, with reference to the Swedish Total Defence System, Swedish Ministry of Defence, January 1991, Section 3.3.2, pp. 80–81.
With respect to remotely delivered mines, the manual states:
The protocol [II to the 1980 Convention on Certain Conventional Weapons] states the special precautionary measures to be observed in the form of recording the locations of the mine fields, or the use of self-destruction mechanisms.

At the Preparatory Conference for the Convention on Certain Conventional Weapons in 1978, Sweden stated that certain limitations on the use of conventional weapons should be agreed upon by the participants including “that minefields on land must be charted when they were laid, so that they could be cleared at the end of hostilities and not remain as permanent hazards to life”.
