[6] From the 1980s, as Cambodia recovered from the massive devastation of the Khmer civil war and the atrocities of the Khmers Rouges regime, Madam Pheap Heak started a small business to buy and sell construction scrap metal, before in 1997 setting up a company called Chip Mong to import fine steel from abroad to supply to Cambodia's construction sector.

[7] From 1990 onwards, Chip Mong began expanding its business by importing cement and consumer goods from neighboring countries.

[11] In December 2010, the Chip Mong Group entered the booming construction sector in Cambodia, relying on ties with both Vietnam on one side,[12] and Thailand on the other, by signing a $200 million joint - venture agreement with Siam City Cement Plc.

[14] Chip Mong recently entered the sector of tourism and hospitality by renovating and expanding a luxury hotel in Daun Penh together with the American multinational hospitality company Hyatt in 2016, finally opening in 2020 amid the COVID-19 pandemic,[15] during which the Chip Mung group along other private investors helped the Cambodian government with major donations.

[18] In March 2021, the three major players of the Chip Mong group were all elevated to the rank of Oknha on the same occasion by a royal decree issued by His Majesty King Norodom Sihamoni.
