Even the Untied States is struggling to scale those out uniformly.
The subsonic aspect requires smaller turbofans - you asked the Chinese - they asked a higher price for it and integration assistance than you are willing to pay.

Keep in mind that a subsonic system going 1500 km and actually being able to make it through AD to that distance are two different things.
