The C919 was described 10 years ago as the wonder that would put Airbus and Boeing in their knees beacause it would cost a fraction of its werstern counterparts. I wonder what the selling price would be today to an outside China airline ?
And similarly the the Sukhoi SSJ , a lot of its componnents depend on werstern parts, which inflated its end price, and it was definitively not a success as expected . so we'll see if this one has a better chance.
As to Chinese only copying , this morning France announced the opening of a factory nickmamed the "Airbus of car batteries" ( joint venture between France, Germany and Italy) , interestingly it says that the technology and the machines/robots used in this fcatory are imported from China,and South Korea, and only these 2 countries have the knowhow and the expertise in this field .A complex transfer of technology agreement had to be put in place.
