MSCI is the world’s most-followed index provider. By the end of 2015, over 6400 clients in 86 countries worldwide use MSCI benchmarks.

An estimated 10.5 trillion dollars of assets are benchmarked to MSCI indices. The MSCI Market Classification Framework consists of three criteria: economic development, size and liquidity as well as market accessibility.

In 2013, MSCI said it put China's A-share under review for its emerging market index, but in June 2014 it decided not to include the A-shares. In 2015, MSCI again held off the inclusion due to limited accessibility and difficulties in repatriation of funds.

By June this year, 421 shares in the A-share market met the entrance requirements of MSCI. And In a possible scenario laid out by MSCI, it could begin with a partial inclusion of 5 percent of A-shares, which will occupy 1.1 percent of the total value of MSCI emerging markets.
