The Barbie movie won’t make it to Vietnam’s silver screens, apparently due to a scene starring the nine-dot line map that depicts China’s claims to disputed waters in the South China sea.
The Warner Bros. film starring Margot Robbie and Ryan Gosling was due for release in the country on July 21, the same date as the US. According to local news website VnExpress, the announcement came on Monday (July 3) from Vi Kien Thanh, the head of the Vietnam cinema department at the ministry of culture, sports, and tourism, who attributed the decision to the National Film Evaluation Council.
Maps featuring the U-shaped vague and broken line through the South China Sea was declared unusable by an international tribunal in 2016. Several governments, including Taiwan, Vietnam, The Philippines, Indonesia and Malaysia, claim stake in the disputed waters. Beijing rejected ruling.
The Greta Gerwig-directed movie isn’t the first to fall foul of regulators because of the map.

Was this the actual stated reason, or is it just "apparently," as the article states. They mention an announcement by some head of cinema but it never actually states what the announcement said.
Stuff like this feels like an op just to keep the "China bad" narrative in people's mind.
I mean maybe it really is the reason but like holy fuck just look at that map. Oddly enough the lines bare a resemblance, but like, why? We live in such an absurd world.
