Beijing has laid on charter flights and ships to move Chinese nationals out of Vietnam after two were killed and 100 injured in violent protests against Chinese oil drilling in disputed waters. Vietnamese warships tried to interfere with the drilling leading to a clash.. More than 3,000 Chinese workers have been evacuated so far. At least 15 foreign-owned factories were torched, some Chinese. Dissident groups are calling for more protests in major cities despite Vietnamese government appeals to end the protests. Beijing accuses Vietnam of not doing enough to stop the anti-Chinese violence.
