Never say never - underestimating a potential opponent is not a great idea. I'd imagine that the DoD, and other countries in the region, are probably going to err on the side of caution about this.
IIRC, the JMSDF have a pair of 20,000+ tonne "Helicopter Cruisers" on the stocks that are enlarged versions of Hyuga and Ise. If the Japanese were willing to go through the political hoops, I'd bet they'd be able to operate JSF. You also have India expanding it's carrier arm as well, both with the ex-Gorshkov and a domestically produced class. They do know how to conduct conventional carrier ops as well, though it was a while ago.
I tend to agree with Gepard - short term, something to keep an eye on. Long term, let's see what the Chinese do with what they learn.
