Chinese here. We followed the Russian/Soviet system of math education for quite a while. The Soviet textbooks were and are still considered superior comparing to our own (from middle school straight to university). They have a certain quality that Chinese textbooks fail to grasp.
Nowadays many schools turn to the American system (I don't know why) and the requirements for math has been dropping for a decade. The inequality of teaching resources is obvious when you compare a student from a privileged school with one from say a country-side school. The government tries to equalize things but it's very difficult to go against the top teachers and rich dads/moms.
