Vietnam has adopted a new film censorship regime that has age related categories including for the first time, an 18 adults only rating.
The new system commenced in 2017 and includes four categories: (P) general audiences and a series of age based rankings C13, C16 and C18.
Officials will classify films based on levels of gore, profanity, violence, nudity and sex displayed, according to an announcement from the Ministry of Culture, Sports and Tourism.
The ministry said it will also consider a film's drug-related content, which must suit a film's content or carry an anti-drug message.
Gratuitous drug-related content will continue to be censored. Censors will likewise permit sex and violence in C18 films so long as it is not gratuitous in nature. However sex and violence, considered mainstream in most countries, in movies
such as Fifty Shades Darker and John Wick 2 is obviously deemed gratuitous in Vietnam. Both films seem to have run into censor trouble.
General Audience films (rated category P) will not contain any horrific, violent or sexual content; they will not make any reference to drug use or production.
Last year, film censors in Vietnam proposed a controversial ban on sex scenes that lasted over five seconds in local films, and full-frontal female nudity. The rules were not officially included in the official rating system for 2017.
Vietnam's cinemas previously used just two ratings, G for general viewers and NC16 for viewers aged 16 and up.
