Nothing official as of now. It is feasible that at some point they might procure FC-1s to replace BAF's aging fleet of A-5s and maybe, just maybe the FC-20 to replace the aging F-7s. And China has always been a very reliable supplier.
But as long as the current government is around, I doubt if anything major would happen. This same government was behind the MiG-29 deal, it was a messy affair.
The reason for the unlikelihood under the current government is:
1. It is extremely anti-Pakistan. So, the FC-1 deal won't go off anytime soon.
2. It has close relations with India. India even fund them during the previous elections. So, China supplying FC-20s is pretty much out of the question, especially since they are stationed on the Indo-China border.
It's sad to see everything is so politicized in Bangladesh, lol.
