Although the Baháʼí community held a generally positive relationship with the government of Ngô Đình Diệm, there is evidence of sporadic opposition at different levels during this period. One account describes government harassment of the Vietnamese Baháʼís around 1958–59, including the imprisonment of the entire Spiritual Assembly of Saigon. On 21 April 1963, Bui Van Luong, then Diệm's Interior Minister, formally prohibited Baháʼís from pursuing "any religious activities in Central Vietnam and the mountainous provinces." Seven months later, the Diệm government was overthrown, and the prohibition of Baháʼí activities was annulled. An account reported in a Swiss Baháʼí newsletter in February 1964 claimed that Baháʼís in Vietnam had been subject to harassment for over seven years leading up to Diệm's ouster.
