An example of the former is the scattered communities of maritime mobile populations or ‘sea nomads’ in the region, including the Moken of the Andaman Sea of Myanmar and Thailand, and the Bajau Laut of the Sulu Sea. State-based nationality laws and registration systems grounded in a system of fixed territorial links struggle to capture the particularities of such populations, who have lived mobile lifestyles for centuries.118 In Chapter 9, Acciaioli, Brunt and Clifton explore some of these issues in the case of trans-border Bajau Laut (or Sama Dilaut) communities of eastern Sabah, located at the interface of east Malaysia and the Philippines and Indonesia. More contemporary forms of cross-border mobility also intersect with statelessness in the region, including labour migration. Irregular migration forms a significant part of this mobility, including human trafficking, both affecting stateless persons and leading to new risks of statelessness.119 In Chapter 7, Kneebone explores the rising phenomenon of marriage migration, especially from Southeast Asia to East Asia, and how its gendered dimension generates risks of statelessness.120 Finally, violent conflict and mass atrocities have generated multiple displacements and forced migration movements across Asia, both historically and in contemporary times. Guo therefore explores the intersection between violent conflict and statelessness in Chapter 5 with the example of stateless ex-Kuomintang soldiers and their descendants in Thailand, noting that conflict and atrocities may lead to statelessness, but equally statelessness may result in conflict and serious human rights violations. These dynamics are also made visible by Kyaw in Chapter 11 on the Rohingya and the ongoing contestations over their citizenship status in Myanmar after the 2021 military coup. Kyaw highlights how politicization of citizenship (and its denial) could be weaponized by political factions for violence and power, and how embedded Janepicha Cheva-Isarakul, and Christoph Sperfeldt, ‘Citizenship and Statelessness among Mobile Maritime Populations: The Case of the Moken in Thailand’ (2023) 27 (4) Citizenship Studies 530. 119 Conny Rijken et al., The Nexus between Statelessness and Human Trafficking in Thailand (Wolf Legal Publishers 2015). 120 See also Susan Kneebone, Brandais York and Sayomi Ariyawansa, ‘Degrees of Statelessness: Children of Returned Marriage Migrants in Can Tho, Vietnam’ (2019) 1 (1) Statelessness & Citizenship Review 169. 118 https://doi.org/10.1017/9781009399555.003 Published online by Cambridge University Press
