Among your local IT companies is there a search engine more popular than Google? A social network more popular than Facebook? A shopping site more popular than Amazon and eBay?<p>For better or worse, the economic and political restrictions China enacted allowed for local companies like Baidu, Alibaba and Tencent (makers of WeChat) to utterly dominate the Chinese market. Those same companies are now pretty much the only competitors that can match the American giants I mentioned before. In this area, this was a big win for China - both for companies and customers (money made stays in the country).
