Excitement at Alibaba's US share debut
The success in Weibo has investors excited about the US stock debut of Alibaba, which is China's largest internet company.
Shares in China's Weibo, a Twitter-like service, rose by almost 20% on their first day of trading on the US stock market, after a lukewarm start.
China's internet market has grown to become the world's biggest with more than 500 million users.
