Chinese ships arrived in Vietnam on Monday to evacuate thousands of Chinese nationals from the Southeast Asian country after the anti-foreign violence resulted in many Chinese casualties last week. The evacuation is an emergency response to the security situation in Vietnam and a non-confidence vote in Vietnam's investment environment.

For Vietnam, the failure to prevent the violence has tarnished its image as a favorable destination for international investment and tourism, which could have severe consequences for its economy, said a Xinhua News Agency commentary.

The social unrest has disrupted the normal operations of foreign-invested companies and undermined the confidence of not only Chinese investors, but also investors from other countries as well.
