I would ban all trade, traffic, transaction, travel to and fro stinkypura.
Anybody caught transferring jiuhu wealth or funds to stinkypura must be charged with money laundering offences.
In this way, PAP-piglets little trick of attacking, manipulating malaysian ringgit, to appreciate stinkypura dollar wrt to malaysian ringgit so that stinky peasants can spend their meagre few S$ in Malaysia and feel like royalty (in their own twisted tiny minds) will be permanently blocked.
Stinkies will be stuck in their teeny tiny hdb peasant slum pigeonholes for long, hot and humid and hellish as it may be, made worse by having to gulp a generous dose of their own pee and poo water called NEWater and without possessing anywhere near the number of vehicles per capita owned by citizens of Malaysia or Brunei (both melayu countries).
to make matters worse, there is of course 160th ranked media.
