I think some countries use local search engines which beat Google when it comes to local search volumes. For example Most popular search engine in Russia and near by countries is Yandex. I think Baidu is the most popular one in China.

Yes, this is correct for multiple reasons, eg censoring (in Russia and China, it's not as easy to get to google as it is in the US).

And either way, in China they really don't have an option to use Baidu or not...
