Qualified Domestic Institutional Investors(QDII) is an investment scheme under which domestic institutional investors authorized by the government could invest in the overseas capital markets under the foreign exchange control system in China.

QDII was initially proposed by the Hong Kong government to introduce mainland capital to the Hong Kong securities market, which was significant to Hong Kong securities market after the Asian financial crisis in 1997. When QDII was first proposed, the China Securities Regulatory Commission(CSRC) was enthusiastic in promoting the scheme. On the other hand, the State Administration of Foreign Exchange's (SAFE) response was lukewarm, due to foreign exchange control concerns. However, now the table has been turned. Due to growing pressure on the appreciation of RMB, SAFE is now more active in promoting the scheme, to maintain the stability of the RMB exchange rate.

Hua'an Fund was the first pilot project for QDII and was only allowed to use hard currency, instead of RMB, for its investment, to reduce risks in connection with QDII. Now, many banks and mutual funds in China are offering QDII funds to Chinese investors to invest in global security markets.
