China has Money and Smart people. (and very effective corporate / nationstate espionage) so they can most certainly reproduce advanced machines.
They might not have incentive yet to do it because it will not make them popular, and potentially output products would be banned on US/EU. They play a long game and want US and EU consumers to ask tehir governments to please allow the chinese products.. so their market share is safe and stable.
I think once there is enough incentive for them they would do it. They simply do not want to do it currently.
