China allows Hong Kong-Shanghai stock trades
China is boosting stock market ties with Hong Kong with new measures allowing cross-border stock investment between Hong Kong and Shanghai.
China's regulator said it would allow mainland investors to trade shares in designated HK-listed firms.
At the same time, Hong Kong investors will be allowed to buy shares in companies listed in Shanghai.
The chairman of the Hong Kong exchange called it a "breakthrough" for the opening up of China's capital markets.
