I'm so confused right here. Why China was still rated as a developing country by dis western idiot? I traveled to d USA and u couldn't imagine almost everything they use there was made in China like electronics, phones, computers and lots more. Samething apply to canada even 9ja, a jamaican friend of mine even told me they use China car in his country. That means china export to all over d world even iPhone was assembled in China, if u got one check d back..... And my question why are they rated as a developing country? And USA, UK and co rated themselves as a developed countries whereas they dont have manufacturing companies as Great China??

They are a developing country. Many Chinese do not have access to those things they produce.
Besides, those goods produced in China are not produced for Chinese markets. It goes like this

Nigeria produces crude oil but does it mean Nigerians have access to petrol, gas, kerosine and others?
Go Google Chinese economy for better understanding.
