TAIPEI (Taiwan News) — Indonesian migrant workers will now be put under centralized quarantine upon arrival in Taiwan starting Friday (Nov. 20), according to the country’s health authorities Wednesday (Nov. 18).

Currently, employers or brokers are responsible for quarantine arrangements for workers, excluding caregivers, from the Southeast Asian nation. The new rule will mandate centralized isolation for all Indonesian migrant workers entering Taiwan from Nov. 20 onwards.

The measure does not apply to those who have obtained a visa by Nov. 19. The move follows a rise in imported coronavirus cases among Indonesians coming to Taiwan for work, said the Central Epidemic Command Center (CECC).

The CECC has also suspended the introduction of new workers by four labor brokers registered in Indonesia: PT. Sentosa Karya Aditama, PT. Vita Melati Indonesia, PT. Ekoristi Berkarya, and PT. Graha Ayukarsa. At least 20 Indonesians hired through these companies have tested positive for COVID-19 once they arrived in Taiwan.

The firms will be not be allowed to resume business until they have presented documentation from the Indonesian health authorities showing that their training centers have improved disease control measures and rid themselves of the virus, said the CECC.
