This week's decision by the mainland's securities regulator to declare all state-owned shares tradable is a step in the right direction after a long period of stasis. However, by itself it will do little to cure the deep malaise that afflicts the country's stock markets.
Since the two stock exchanges were founded in the early 1990s, almost 66 per cent of all the equity of listed companies has been held by state bodies and other so-called 'legal persons' and designated non-tradable.
The resulting shortage of liquid stock was instrumental in driving the A-share markets to giddy heights in 2001.
Fears that Beijing was about to change the rules and sell state shares, flooding the market with new stock, helped drive them down again.
With the market now down 54.5 per cent from its peak, the authorities have finally been prompted to act.
While the state shares are not the only factor depressing A shares - poor corporate governance, opaque company accounts and dishonest brokers have also dragged down prices - investors have increasingly argued that no sustainable recovery is possible unless the overhang is resolved.
