The biometric system is catching 45,000 overstayers... This would have been when they were attempting to depart the country (self-deportation)... and now they stay even longer. Or did they want to say that they caught people trying to enter who had PREVIOUSLY been an overstayer and were banned from returning?
First time I was there was April 2016. Beautiful water and not too crowded. Some Chinese tour groups but manageable. Last time I went was May 2019.. overcrowded ferry to get there, hordes of mostly Indian tourists and some Chinese. If they are adding 7000 Chinese to what I saw, there is no reason to go anymore. They do have some small accommodations there, but I never spent the night there..
