Taiwan security agencies have been looking at whether to raise the alert level for travel to certain countries for its citizens, the official said. Reuters was not able to establish whether any decision had been made on the alert or the countries for which that review was underway.
Taiwanese in Cambodia, Laos and some unspecified African nations could risk being taken in for investigation on suspicion of backing independence, the official said, citing Taiwan's assessment of the development and speaking on condition of anonymity.
"They might be taken for questioning by the local or Chinese police there, at least to psychologically intimidate them," the official told Reuters.
