"Barren pieces of land". Yes they are not underwater all the time. Is that what you mean by barren?
They don't want or require your "help"....beyond conventional economic ties.
India exports are lately nearing 7 billion USD to Bangladesh. Bangladesh exports about 500 million USD to India lately. That is 14: 1 in favour of us. 500 million USD is definitely next to nothing. Plus look at the trend:
Exports to India not rising despite efforts | The Daily Star
India exports about 16 billion to China and China exports about 58 billion in 2014. That is nowhere near a ratio of 14:1. Rather it is about 3.5 to 1.
If you were exporting the same ratio to us like we do with China, your exports would be around 2 billion USD (4 times higher)....not a measly 500 million USD....and 16 billion is definitely not next to nothing like 500 million USD is (even if you include the population difference).
Its fine, you are helping to finance the illegals you have living in India through the major trade deficit you have with us.
