BNS Bangabandhu has A 244 light weight torpedo which has range of just 13.5 km.
MN Kilo has Klab Anti Ship Missile and it has also got Type 53-65 torpedo with 18 to 22 km range.
Type 035 Ming class is just an improved Soviet Romeo class with outdated hull design whereas Kilo is a new design...
But we already have large number of medium range SAM. And we have a production line for KS 1B SAM. So inducting more new type will make the integration more difficult. What we need is a long range SAM systems to replace Volga M.
