Just 14 factories targeted in Vietnam's anti-China protests belonged to mainland Chinese

Of 351 plants damaged in one province, just 14 are mainland Chinese-owned, official report says

Only a tiny fraction of the factories looted and damaged in the violent anti-China protests in Vietnam last week were owned by mainland Chinese enterprises, according to an internal Vietnamese official survey seen by the South China Morning Post.

Taiwanese businesses bore the brunt of the two-day frenzy of arson, vandalism and theft as initially peaceful protests triggered by Beijing's move to drill oil in disputed waters off the Paracel Islands ran out of control.
