for long-term Vietnamese Cambodian residents, in accordance with Cambodian law, have been rebuked by the Cambodian government.59 This registration process was subsequently accompanied by systematic confiscation of prior documentation that authorities deemed to be ‘irregular.’60 The Ministry of Interior identified at least 70,000 mostly Vietnamese ‘foreigners’ holding such irregular documents.61 In the provinces monitored by Minority Rights Organization, authorities have confiscated the majority of legal documents previously held by ethnic Vietnamese residents, including birth certificates and old immigration documents, in some cases Cambodian identification cards and family books. Officials seem to have deemed irregular or illegal most documentation previously issued by other, mostly local Cambodian authorities. The confiscation of such legal documentation will make proof of long-term residence in Cambodia even more difficult for affected individuals in future.62 Challenges with data: There is currently no reliable, public data available about the size of populations of Vietnamese origin in Cambodia generally, and those affected by statelessness in particular. This has both to do with the sensitivity of the topic and the fact that Cambodia does not recognise affected individuals as statelessness, and as a consequence does not record or collect such data. More generally, official statistics about Vietnamese populations in Cambodia have been inconsistent, and questions remain about the quality of data and the appropriateness of categorisations. The last 2019 national population census recorded 78,090 people whose ‘mother tongue’ was Vietnamese.63 Around the same time, based on the results of the ‘foreigner’ census, the Ministry of Interior reported a figure of 180,690 ‘Vietnamese (nationals)’ residing in Cambodia, of which 69,413 were classified as ‘old settlers’.64 This figure seems to be roughly in line with the almost 90,000 ethnic Vietnamese individuals who had received the PRCs, considering that children under the age 59 Narim Khuon (2019) ‘Kingdom Rejects Vietnam’s Request to Provide Citizenship to its Nationals’, Khmer Times, 21 August 2019. <https://www.khmertimeskh.com/635604/kingdom-rejects-vietnamsrequest-to-provide-citizenship-to-its-nationals/> (6 March 2023) 60 Sub-Decree No. 129 on the cancellation and withdrawal of irregular Cambodian administrative documents possessed and used by foreigners (2017). 61 Ben Sokhean (2020) ‘Interior Ministry Sees a Danger to Kingdom: Illegal Immigrants ‘Are a Security Risk’ Khmer Times, 14 July 2020. <https://www.khmertimeskh.com/744331/interior-ministry-sees-adanger-to-kingdom-illegal-migrants-are-a-security-risk/> 62 This section has drawn from Sperfeldt, Christoph (2021) ‘Legal Identity and Minority Statelessness in Cambodia: Recent Developments,’ Statelessness & Citizenship Review 3(2): 347-353. 63 National Institute of Statistics, Ministry of Planning (2020) ‘General Population Census of the Kingdom of Cambodia 2019’, Final Census Results, 25. 64 ‘Report of the Special Rapporteur on the Situation of Human Rights in Cambodia: Comments by the State’, UN Doc A/HRC/39/73/Add.2 (11 September 2018) 23-24.
