Buy chinese internet company sina?

Sina (nasdaq: sina) is the 2nd most popular internet portal in China right now and is 6th in the world for yearly web page views. Given that China's internet market is a young and rapidly growing one I was thinking of buying some Sina to hold (5-15 years) in the next couple of days. It can be compared to yahoo here while the number one company Baidu (bidu) is comparable to a google. However Baidu trades at something close to 116 times predicted 2006 earnings while Sina trades at about 21 times. The stock also took a slight dip recently after some bad advertising expenses but they have 288.6 mil in cash and investments and 100 mil in convertible debt.
Some quick stats from the stock quote-
Current stock price $25.4
P/E $31.36
Earnings per share Q4 2005 are expected to be $.23 and Q2 estimates for 2006 are steadily rising to $.25.

Anybody wanna give me a "yeah that sounds like a great thing to buy" or "man your stupid" analysis of this stock Im thinking about buying?
