Multiculturalism is the source of identity, innovation, and creativity, helping to connect all countries in the world. Therefore, building a happy and civilized multicultural family is the goal of every country and everybody. Vietnam and South Korea officially established diplomatic relations on December 22, 1992. Over the past 30 years, the two countries relations have developed rapidly and positively in many fields such as politics, investment, trade, tourism, and culture. The number of Korean- Vietnamese multicultural families increased due to the demand for a stable and happy marriage. However, differences in language, especially culture, make vulnerable family members (women, children) face many difficulties such as unhappy married life; education issues; naturalization issues; repatriation; community reintegration. The purpose of the study is to ensure the interests of members of multicultural families and to promote cooperation and friendship between the two countries (Vietnam - Korea) in the field of culture. This study focuses on the disadvantaged group of repatriating women and children. With the content: "Policy recommendations for supporting the repatriation of women and children - A family practical study in Vietnam”, the study focuses on clarifying: (i) Some suggestive situations; (ii) Difficulties; (iii) Proposing some solutions. The research was carried out by specific methods such as (i) Literature review; (ii) Analysis of available statistics; (iii) Practical research through the qualitative survey (in-depth interviews with vulnerable groups (including women and children)). The purpose of the study is to ensure the rights of repatriating women and children, thereby improving the efficiency of cooperation and friendship between the two countries (Vietnam - Korea) in the field of multicultural management.
