ahahahha......i agree, when i watch Indians and bengladeshi having disagreements/arguments on here, they remind me of China and Vietnam relationship. I dont understand why India feels threatened/worried about Bengladesh buying submarines/frigates from China(when India cant provide this itself, since it cant produce this independently or it cant meet its own defence needs to be able to export frigates), since Bengladesh is no match for India militarily in any naval conflict, same with Vietnam being no match for China in any naval conflict/militarily. So dont understand why both country are worried about what their smaller neighbour buy abroad.
It not about capacity, its about political or strategic control. More correctly its indian insecurity, feeling that in some way China is encroaching into "indian sphere of influence". What indians need to understand is Bangladesh will buy what it thinks it needs and can afford from where ever, regardless of what india thinks or says.
1. Bangladesh has a very small defence budget, and only spends around 1.2% of its GDP on defence, even less then myanmar which is a third its size. So it has to buy where it can get value for money, China and Russia.
2. India really does not have that many exportable/marketable weapon systems (ALH, Bhramos are only a few), plus a exporter needs to provide timely delivery, support, training, finance, marketing etc...not something indian PSU are good at.
3. Even if india could provide comparable solutions, no nation would purchase systems developed from a potential threat.
Now, no Bangladeshi would argue that india is ten times our size or that we could win a war with india. What we dont like is indians telling us what we can or cant do. And as our economy grows we will be able to afford more and more weapons, whether its chinese or its russian is upto us.
