Timing for 'through train' is right, says economist Andrew Sheng
Former Securities and Futures Commission chairman Andrew Sheng answers questions from Nick Edwards on the 'through train' plan to integrate the HK and mainland markets

The "through train" is the culmination of nearly 10 years of co-operative efforts between the Hong Kong and mainland authorities on the integration between the two stock markets. This was tried earlier in 2006 and 2007, but the timing was not ripe and the process was delayed by the 2007 to 2009 recession.
No. Chinese reforms are always pilots that test the waters and enable the market to experiment until the systems and regulatory tools are "prototyped" before full opening. This opening is significant - the size itself can be adjusted quickly if need be.
Everything is a matter of timing. Individual and periodic approvals of quotas, both inward or outward (QFII and QDII) are arbitrary decisions that lag market decisions. As the exchange rate is closer to the equilibrium level and there is more latitude for two-way movement of the RMB, pricing of the A and H shares will converge, as it is already doing, and if the mainland economy recovers after reforms, the potential for greater Hong Kong and foreign participation in mainland markets and vice versa will be enhanced.
