Regulators of China's NASDAQ-style growth enterprise board (GEB) are working overtime to iron out the thorny issues arising from the conflicting interests of the various market participants amid the countdown to its launch later this year.

The urgency of the matter was brought to the fore during a forum organized by Shenzhen Stock Exchange recently in Shenzhen. More than a dozen attendees, representing the exchange, the China Securities Regulatory Commission (CSRC), and market intermediaries participated in the forum.

Among the key issues hotly debated were the cost of listing, duration of the lock-up period and supervision of advisors and sponsors.
