The nationwide unrest, the worst to hit in Vietnam years, followed Beijing's deployment of a large oil rig in a patch of the South China Sea also claimed by Vietnam.
Both nations have sent ships to the waters that are now locked in a tense standoff with each other, raising fears of possible conflict.
The boats with a capacity to carry 1,000 passengers each arrived at Vung Ang today, said a port official who wasn't authorized to speak to the media.
Vung Ang port is part of a large Taiwanese steel mill complex 250 kilometres south of Hanoi that was overrun by an anti-China mob last week.

Two Chinese workers were killed and 140 injured in the incident, the most serious in nationwide unrest in which several factories and industrial parks were attacked.
Many factories were not Chinese-run but Taiwanese or from elsewhere in Asia, apparently targeted mistakenly or by gangs intent on looting.
The riot on Wednesday and Thursday took place at a complex operated by the conglomerate Formosa Plastics Group, Vietnam's largest single foreign invested project. Linh said the complex employed 3,000 Chinese citizens.
But since the rioting they have cracked down, aware that the violence threatened the country's reputation as a safe and cheap destination for foreign manufacturers to establish factories.
