Cambodia’s porous borders, poverty and geographic location render the country a major point of origin, destination and transit for irregular migrants. An increasing number of Cambodian irregular migrants are apprehended in neighbouring countries. Government operational and administrative capacity needs to be enhanced in the area of migration management. Responses include cross-border technical cooperation, capacity building with regard to bilateral and regional border checkpoints, preventing migration-related crime, awareness-raising on the risks of irregular migration and improving labour migration management.

Counter Trafficking

Trafficking in persons remains an increasing concern in the country and surrounding region. New trends include women being subject to forced marriage abroad and the increasing number of male Cambodian victims indentified in forced labour trafficking situations within the regional fishing industry. As Cambodians continue to migrate abroad through irregular channels, risks to human trafficking and labour exploitation increase. Recent trends have shown that more and more Cambodian men are abused and exploited in the regional fishing industry, having been trafficked through neighbouring countries and ending up stranded further abroad. With the support of the international community, including IOM, the Government of Cambodia (GoC) has built a comprehensive legal and institutional framework to address trafficking in persons. However, much remains to be done to foster the effective enforcement of the provisions adopted, while a need for clarifying the roles and responsibilities of relevant government agencies involved in eliminating trafficking has been emphasized most recently. Cross-border cooperation with neighbouring countries, notably with Thailand and Vietnam, has also been indicated as a key area in need of improvement for prevention, protection, return of victims, and prosecution of perpetrators. While regional partnership and formal agreements have been developed, implementation of such agreements remains challenging on both sides of the border.

    In response, IOM is providing technical assistance and coordinating programming through the National Committee to Counter Trafficking, including other important line ministries such as the Ministry of Foreign Affairs and relevant consulates involved in the voluntary repatriation of victims, the Ministry of Social Affairs, Veterans and Youth Rehabilitation (MoSVY) on provision of victim assistance and reintegration support with an expanded focus on adult male victims of trafficking, given the lack of services available to this particular group. Through the project, direct assistance is provided to trafficking survivors upon return to Cambodia, including medical aid, food supplies and temporary accommodation. The provision of direct assistance is complemented by capacity building, such as training on victim identification, psychosocial support and case management to Government and NGO service providers.

    The health of trafficking survivors is a priority of the IOM Cambodia mission’s victim assistance. The recent collaborative research into the health consequences of trafficking between IOM and the London School of Hygiene & Tropical Medicine helped to explore the health risks, consequences and safety and service needs of people using post-trafficking services in the Mekong countries.

    Technical Cooperation and Border Management

      In the area of technical cooperation, IOM provides support to strengthen Cambodia’s institutional capacity for effective migration management. In particular, IOM concentrates on enhancing national administrative and operational capacities to combat irregular migration, human smuggling and related cross-border crime. IOM promotes cross-border and interagency cooperation in the region, with particular reference to information exchange, building operational and administrative systems related to border management and law enforcement.

      In particular, IOM provides capacity building training to frontline border control officers, who deal with millions of travellers and migrants to effectively detect and respond to cases of human smuggling including travel document examination.

      Labour Migration

        In the area of labour migration, IOM focuses on building Cambodia’s administrative and operational capacity, particularly in improving the effectiveness of regular migration procedures and the protection of migrant workers. IOM also aims to increase regular labour migration options, provide assistance in securing opportunities for Cambodia’s skilled and semi-skilled migrants and raising awareness on safe labour migration through targeted information campaigns and establishment of migrant resource services. IOM aims to support the RGC to enhance management of outward labour migration flows to neighboring countries, particularly Thailand and Malaysia, with an emphasis on reducing the instances of abuse through the effective implementation of recently adopted ministerial regulations; facilitating prospective and returned migrants’ access to updated and reliable information; and improving migrants’ access to recourse and compensation mechanisms.

        Health Promotion and Assistance for Migrants. IOM is committed to enhancing the capacity of the Cambodian government to understand and appropriately meet the health needs of vulnerable migrants and mobile populations, with a particular focus on cross-border migration and communicable disease control. Along the Cambodian borders with Thailand and Vietnam, IOM aims to enhance the capacity of the government and local partners to respond to the health needs of vulnerable migrants and mobile populations. The recent TB REACH initiative to increase early detection and treatment of TB among irregular migrants returning from Thailand is an important first step in the development of migrant-sensitive health services in the border provinces and is key to mainstreaming active case finding among high-risk groups within the National TB program.  Learn more: Increasing Active TB Case Detection for Returned Irregular Migrants at Poi Pet Border  |  Watch video: Cambodia: Detecting, Treating TB in Vulnerable Migrants

        Migration, Climate Change and Environmental Degradation

        Cambodia is considered one of the most hazard-prone countries in South-East Asia. The country, characterized by a tropical monsoon climate, has observed important climate changes as an increase in mean temperature, alterations in the timing and duration of the seasons, an increase in frequency and intensity of extreme weather events and the sea level rise. In particular, floods and droughts are the cause of hundred deaths and of major agricultural crop losses.

        IOM is supporting the Royal Government of Cambodia’s initiative to respond to the growing threat of climate change through the integration of the issue in the national agenda. IOM aims to enhance awareness and knowledge of Cambodian policymakers on the link between climate change, environment and migration. Watch video: Rising Above Natural Disasters: My Village's Story

        Facilitating Migration

        The IOM office in Phnom Penh is the designated Canadian Visa Application Centre (CANVAC) visa application submission site on behalf of the Citizenship and Immigration Canada (CIC). IOM staffs assist applicants by verifying that application forms and all necessary documentation are complete and present before forwarding the application to the Embassy or Consulate for processing.

        Incomplete or improperly completed applications may cause unnecessary processing delays, therefore IOM’s experienced visa application counselors assist migrants to submit application as per Citizenship and Immigration Canada (CIC) guidelines. Counselors advise applicants of all procedures and requirements, fill-in and print out all required CIC application forms, facilitate assembling of all required supporting documentation, and submit the completed application to the relevant Canadian visa processing post.

        IOM aims to assist migrants before, during and after their travel. To do so, IOM provides travel assistance such as flight bookings, and assists migrants at the airport with all Cambodia exit formalities, facilitates group travel for Cambodians traveling for resettlement, and notifies sponsors at the destination of all travel details in advance. Learn more: Travel and Visa Application Support Services for Migrants
