Looks like the FC-31 was chosen by the Chinese Navy.
I imagine you would've read the piece... the last paragraph pretty clearly says (even through translate):
"Could the FC-31 finally serve under the flags of the Chinese army, like what can be seen recently in a TV report where a model of FC-31 in livery PLA Navy is seen behind an officer of the Chinese Navy interviewed? Or will the Chengdu J-20 end up monopolizing the Chinese VLO combat device market for the next three decades thanks in part to
? We could hope to have a (first) answer in the months to come ..."
In other words, it's still up in the air.
Putting it another way, the title of the piece is a question (FC-31 chosen by the Chinese Navy?) -- and the answer is "no, still to be decided". Punctuation is important
