"an investigation is ongoing, with China's government overseeing."
Their investigation is useless. You will see this type of incident happening again and again. Investigation is all for show, and nothing will be done to improve their safety.
The Singapore government should implement caning for these foreign criminals coming in to commit crimes. If not, we will continue to deal with these scums time and again.
Don't blame the smart when you and your kind are stupid enough to believe in a flying donkey. See how smart the Chinese are? Even if the Malaysian gov were against them, they still have 80% of the top 100 private companies.
And why do you think they want to leave Malaysia if they were treated equally? I don't see many Malay Singaporeans migrating to Malaysia to change their passports. Maybe buy house there for retirement but still keeping their Singaporean passport.
