[contingencies]

Ultimately it depends what you want it for. I usually live in Asia so some info there follows...

.sg = low corp tax (first 3(?) years waived). someone else here mentioned capital gains scenario. stock market secrecy regime is designed for laundering burmese drug money. US lapdog. its boring as batshit... see https://en.wikipedia.org/wiki/Disneyland_with_the_Death_Pena...

.hk = low personal tax (none, unless resident >3 months/year). can open business and bank account within 2 hours (pay an agent). first world level of service. less US-friendly and more fun than .sg.

.cn = low chance anyone will come looking at your balance. basically no tax. nice forex trajectory for CNY at the moment. only way to really do business in china. possible to convert inbound international SWIFT xfers to EUR/USD/RMB cash, even without a bank account, with any foreign 'id' document. online banking is crap. foreign banks are barred from providing most services despite china signing to the contrary when joining the WTO. ~impossible to process card not present credit card transactions. its bladerunner meets monkey magic meets the land of opportunity. taobao is a big win if you ever do hardware sourcing.

other countries in Asia tend to lack decent english or infrastructure, but may provide interesting fringe benefits (eg. IIRC Philippines gives you permanent in/out visa with a property purchase, has lots of good english speakers, though they recently dropped their relative bank secrecy to US pressure)
