Private Banking in China

Private banking businesses have been booming in China. There are several banks that offer private banking services, such as :

• Citibank
• Standard Chartered Bank
• Industrial and Commercial Bank of China ( ICBC )
• Bank of Communications

Because China economic are still growing, so the cake is big enough for bank investors. That's why HSBC also launched private banking services in China. Because of their target market is wealthy people so the minimum initial deposit for an account is one million dollars. I am wondering what privileges for wealthy investors.
