Pakistan was one of the 45 countries which contributed to the UNTAC operations in Cambodia from 1992 to 1993. Since the contingent did not have their own military mail service, Cambodia Post and the French military mail franchised by Cambodian Post for international delivery were the two options for them to send letters.
Here is a Phnom Penh to Lahore mail sent by a Pakistani UNTAC CIVPOL Kampong Speu Province inspector. Although he was in Phnom Penh, he used the UNTAC Bangkok Headquarters PO Box as his return address likely because of the unreliable incoming mail service of Cambodia Post at the time.
The cover was machine cancelled at the Phnom Penh Central Post Office on 27th October 1992 with an arrival postmark of Lahore on 18th November, it was a 3 week travel. Due to rapid inflation and shortage of high denomination stamps, postage meter was extensively used on mail in 1992, this cover is a testimonial of the phenomenon with 410r meter postage and an additional 6r postage stamp franked on the far left of the cover.
The following is a Pakistani UNTAC mail from Phnom Penh to Lahore handled by the French military mail franchised by Cambodia Post for international delivery. This service was offered from July 1992 to November 1993.
The Pakistani battalion did not only helped in the electoral support in Preah Vihear Province as assigned by the UNTAC, mine clearing, disarmament of different fractions, infrastructure repair and strengthening, language and vocational training for civilians are among many of the aids provided by the more than 1100 Pakistani contingent members from May 1992 to August 1993.
