'Barbie' may be banned in the Philippines after Vietnam.

Controversy surrounds the Barbie movie due to a scene featuring a disputed South China Sea map. 

The Philippines and Vietnam may ban the movie for including the contentious nine-dash line. 

The movie is currently under review by the Philippines' regulatory board. 

A senator is urging a block on the film, citing sovereignty concerns. 

Warner Bros. defends the map as a "child-like" doodle with no political statement. 

The territorial claims in the South China Sea are complex and overlapping. 

The inclusion of the nine-dash line is viewed as endorsing China's claims, causing outrage. 

Editing the map out of the movie is proposed as a potential compromise.
