Chinese tourists could be PLA’s ‘fifth column’ against Taiwan

Wu said Taiwan’s increasingly open policies have opened more channels for mainland Chinese tourists to visit the island for tourism, education, employment and commerce. More than 3 million tourists from mainland China visited Taiwan last year. This is a huge number which gives the PLA a great opportunity to deploy “undercover” troops to the island prior to an invasion, Wu said, as just 1% of this number is equivalent to two divisions of PLA ground forces.
