Thousands protest in Vietnam over China oil rig

Anti-China protests have erupted at an industrial park in southern Vietnam amid tensions over territorial rows in the South China Sea, the BBC reported.

The park's management said three factories were set on fire on Tuesday. No casualties have been reported.

They said protestors targeted factories owned or managed by the Chinese, and Chinese expatriates.

The protests come after China moved a drilling rig into waters claimed by Vietnam earlier this month.

The management of the Vietnam Singapore Industrial Park (VSIP) said that protestors gathered on Monday in Thuan An town, in the southern Binh Duong province.

On Tuesday they moved on to VSIP's two industrial parks nearby.

A spokesman for VSIP told the BBC the three factories were set on fire on Tuesday night after workers had gone home.

Not all of the tenants of the three factories were Chinese companies, she said. Some Taiwanese companies had been affected.

Other reports suggested the violence was more widespread, with more factories targeted.
