Russian search engine Yandex is teaming up with Maxthon, a popular Chinese browser. Their partnership will yield a Russian language version of the browser. Of course, Yandex will be set as default on the browser.
Yandex is the leading search provider in Russia and the second largest in Europe. comScore has Yandex at 44% of the Russian search market and Google at just 10%.
Meanwhile, Maxthon's global browser share was 1.55% in August 2009, according to Net Applications. Their largest overseas market is Russian, so the partnership with Yandex certainly makes sense.
