China A-shares will not be included in the MSCI Emerging Markets Index as part of the 2014 Annual Market Classification Review, but will remain on the review list as part of the 2015 Annual Market Classification Review, said a statement issued by the indexes provider on Wednesday morning.

This decision is based on feedback highlighting remaining constraints on investments linked to the QFII and RQFII quota systems received from international institutional investors in a consultation launched in March 2014, MSCI said.

Earlier report issued by CITIC Securities, China's biggest brokerage, said including A-share into the index may attract $30 billion from the global market. Some analysts said the fresh capital outside China will help to boost the sluggish stock market in China. But the hope melted on Wednesday.

Investors stayed calm when the message came Wednesday morning. The benchmark Shanghai Composite Index retreated slightly by 0.14 percent to 2049.69 by 11:00 am.

Because of the significant size of the China A-shares market, the possibility of further regulatory reforms and other changes expected in the near term, such as implementation of the Shanghai/Hong Kong Stock Connect program, it is important to continue to engage with the international investment community on the potential inclusion of the China A-shares in Emerging Markets as part of the 2015 Annual Market Classification Review, MSCI said.
