Hong Kong investors are eager to buy yuan assets to capitalize on the currency's expected appreciation against the US dollar, according to a survey published on Thursday by China Construction Bank (Asia).

The survey, which polled 805 people in Hong Kong with at least a HK$10,000 (US$1,288) monthly income, found that more than half of the respondents believed that yuan savings were an effective investment, and an essential part of a good investment portfolio.

Over 40 percent said they will buy yuan deposits over the next 12 months, while 58 percent of respondents agreed that "looking back on the past three years, I should have invested more in RMB".
