Is it better invest in a similar ETF in HKEX instead of US or UK markets for long term ETF investing due to taxes?

I don't know how much things have changed since about 3 years ago, but back then I could not find a decent HKEX broker in singapore to buy and hold shares/ETFs at a decent fees. even though there is no dividend or capital gains tax in HK, the broker custodian fees alone was too high for my liking. thus, i went for US broker and more recently, robos to gain exposure into US.

another thing to take note of is the expense ratio. on surface you might see HK has no tax, but it could all be already taxed at source (ie at US). so even if there is such ETF, the price or NAV of the ETF could already reflect all the taxes nett off.

hope this helps.​​​
