A plan to link the stock exchanges in Shenzhen and Hong Kong is "underway", an official from Shenzhen said on Tuesday.

"Shenzhen will further cooperate with Hong Kong in the financial industry, talent exchange and mutual fund recognition," said Xiao Zhijia, deputy director-general of Shenzhen's Office of Financial Development Service.

Xiao added that the authorities in the southern Chinese city will actively promote the launch of a "through train" stock trading system similar to what is being launched between Hong Kong and Shanghai.
