Taiwan extends ban on Indonesian workers 

Taiwan’s government on Wednesday extended a ban on Indonesian workers coming to the island for an indefinite period citing a surge in the number of infected people arriving and lack of cooperation from Indonesia’s government in verifying documents.

Since the start of October, Taiwan has recorded 132 positive cases in arriving Indonesian workers, of whom 76 carried negative test results with them when they landed, the Central Epidemic Command Center said

Taiwan last month announced a two-week suspension for the entry of Indonesian workers, which the government will now extend, the Central Epidemic Command Center said.

It did not give a date for when it will re-open entry for the workers, only that the government will make the decision depending on the pandemic situation in Indonesia.

Since the start of October, Taiwan has recorded 132 positive cases in arriving Indonesian workers, of whom 76 carried negative test results with them when they landed, the center added.

Taiwan's "health minister" Chen Shih-chung told reporters that represented an unacceptable risk to the island, and that Indonesia’s government was being uncooperative.

“To date the Indonesian authorities have been unwilling to cooperate in verifying the documentation,” Chen said, referring to the pre-arrival coronavirus tests which are now required for almost everyone arriving in Taiwan.

Some of the Indonesians who have tested positive in Taiwan did so at the end of their mandatory 14-day quarantines, and not all have had symptoms.
