Dayco Belts - manufacturing moved out of USA

Has to be.
My guess is the marketing folks know there's a segment of buyers that China would catch their attention.

For belts it should be pretty easy to cross reference to other brands.
If they've moved hoses to a different plant, I'm going to be a little bummed. I've found different companies hoses are often a little different even though they cross reference as the same. Its been good to have a choice when trying for the best fit.
PRC and they smell like the inside of a Harbor Freight store LOL
