SINGAPORE - On Wednesday, Prime Minister Lee Hsien Loong called out festival goers for not picking up their litter, and asked Singaporeans to make Singapore a clean city rather than a "cleaned" one.
A day later, Emeritus Senior Minister Goh Chok Tong has taken to Facebook to do the same.
Comparing Tokyo and Singapore, he said that the Japanese capital had no rubbish bins in public places, but it is still litter free.
"Without foreign workers, Singapore is likely to become a 'garbage city'," Mr Goh said in the post.
Last Saturday, Meadows by the Bay was covered with discarded plastic ponchos, cups and other garbage after 13,000 festival goers attended the Laneway music festival there.
