Then make appointments with OCBC, DBS, Citibank, and Standard Chartered. You can probably even go back to Hang Seng and HSBC and approach them as a wealth management/private banking client.
LGT is a good bank. But besides not being the kind of bank
@providenceventurer is looking for and AFAIK 5 million isn't enough (10+ last I saw), if someone were to bank with LGT, might as well just go with LGT in Liechtenstein and not some far-flung Asian outfit.
Never really understood why people go to places like Hong Kong and Singapore only to work with European/western banks, unless it's to bridge a interregional business interest. HSBC, Citibank, and SC are different in that their Asian presences are so strong (retail, commercial, and wealth management). Banking with LGT in Hong Kong makes about as much sense as banking with Bank of China in Luxembourg.
