looks like you really need to educate yourself on manufacturing, assembling et al. Suppliers does NOT mean they make it. For example Foxcon is located in China and assembles iphones - they are therefore a key member of the supply chain. But they are shipped parts from all over the globe.
I am not going to try and sort out differences between news items. iPhones 6 has been out and it has shipped with gorilla glass. Gorilla glass is made by Corning. This is well known and if you doubt it, knock yourself out searching.
If you doubt the 2 to 3% number (I have already given you source), show me what the China's share number is with proof.
assembly is assembly, supplier supply components, you are an idiot
the news told you that Lens is a supplier, not a assembler.
besides, let me repeat, batteries and systems are from China's DESAY and Sunwoda, acoustic components are from China's Goertek and AAC Technologies, Taptic Feedback components are from AAC Technologies
you have not given me the source about the numbers
