Good to know, but the main thrust of my question was if the current priority for 5* Chinese tanks also applies to the factory or is it only for core-based recruiting purchases at Mandy's store. 'Boosted drop rates' is a bit vague, considering that there's a random 'drop' element to both store purchases and factory construction. Yet the only place you can see the increase advertised inside the game itself is in the store where you spend cores to recruit tanks.
