China's central bank on Thursday unveiled a technical guideline for foreign investors' yuan-denominated activities in the mainland's equity markets, moving a step closer to opening its capital markets and promoting the yuan's overseas use.

The guideline on the implementation of the Renminbi Qualified Foreign Institutional Investor (RQFII) pilot scheme is part of the latest efforts by the central bank to regulate a potentially booming market with the backflow of yuan from overseas.
