"Some Chinese citizens visited Andaman and Nicobar Islands, which are restricted areas for foreigners, without gaining permits from India. Some tourists were asked to return upon arrival; some were even arrested or investigated," said the advisory, reported the state-run Global Times.
According to the report, the Chinese Embassy in New Delhi issued the warning on Tuesday.
The advisory also elaborated how Chinese tourists were denied entry or investigated while travelling in India and how the Embassy had to step in.
The first advisory was issued on July 7, asking Chinese to reduce unnecessary travel to India. It was reissued on August 24.
