50 Riels Bon Touristique

Cambodia's Ministère du Tourisme issued these bon touristique notes as a parallel exchange instrument — foreign visitors were required or encouraged to convert currency into these vouchers, which could then be spent at approved hotels, restaurants, and state-run facilities. The system was a common device among mid-century socialist-leaning governments seeking to control hard currency inflows and keep tourist spending within sanctioned channels.

The 1960s timing places this squarely within Sihanouk's neutralist period, before the country's catastrophic slide into the conflicts that would consume the following decade. Tourist infrastructure was modest but real — Angkor Wat visits were actively promoted abroad, and the voucher system supported that effort.

Survival rate for bon touristique issues is generally low; they were meant to be spent, not saved.
