J-10CE is officially available for export as per public data.
But hard to say what the availability of it is for Bangladesh. Also, is it wise for Bangladesh to buy Chinese planes when they are time and time again failing to support the BD position on Rohingya.
We DO need China ultimately for India.
But until the Rohingya problem is settled or actually until there is a new government in Myanmar, that nation will be the main problem for Bangladesh.
That said, it may be wise to get into the Western fighter ecosystem.
Really I would be good with F-16, Typhoon or Gripen but so far only Typhoon has been linked to Bangladesh and even that is a very vague link officially and rumors unofficially.

In regards to the Typhoon all I can say is Inshallah!
