Vietnam is not in the Bluebook Table 2 for Foreign Jurisdictions. (as of 1/30/2025)
Per the Greenbook, Vietnam does not have a uniform format to cite to legal sources.
Some sources for citation:
My suggestions for citation format:
Constitution
Constitution of the Socialist Republic of Vietnam, ch. 2, art. 43, https://ccc.gov.kh/detail_info_en.php?_txtID=791 (unofficial English translation).
Short Form: Const. Kh.,art. 43.
This is a cite to the most current Constitution and Amendments (1992 Constitution, with the most recent amendments, the last of which was 2013.)
