In China, the best universities are Qing Hua and Bei Da. I'm not sure what that is in English. I'm not even sure where Qing Hua is (probably in the city of Qing Dao) but Bei Da is Beijing University, I suppose.
The thing is, Chinese Universities appear to have entire departments which splinter off to form new Universities, so you have things like Beijing University of Agriculture, which isn't prestigious at all. It's quite a confusing system.
USA: Yale, Princeton, Harvard, Berkeley and I suppose UCLA would sorta count too.
Canada: University of Toronto has direct ties with Oxford, apparently.
