China has, but, lets not over play it, we have done a lot for China as well.
And, a lot of countries have done a lot more for other countries, then China has done for Pakistan, its good to keep things in perspective. If you want examples, I can provide plenty. But, they only helped Pakistan, because we helped them and stood by them when they needed us, it has never been a one way street. because they are bigger, they were able to do more, but please do not think it was out of goodness of their heart.
The only way to make yourself secure and grow wealth, is by reducing the number of enemies, and increase the number friends. Not having friends is less important then not having enemies. You can still work together without being friends, but having enemies means, there is always someone out there actively working against your interests.
Making peace, and working with everyone is the only way forward, there is no other answer, it really is that simple.
America is still the most powerful country in the world, but it has become weaker. Do you know why it has become weaker, because it has hurt its allies, even the most powerful country in the world needs friends to be strong, please remember that. So, friendship with Bangladesh is good for both countries, them and us.
Can you give me a list of countries who have done more for other nations than what China has done for Pakistan?
Self sufficiently and success as a nation is NOT dependant on having a few enemies. Russia and Israel are prime examples of that. Also what do you do when the very existence of some nations and their core beliefs are the hatred of your nation, it's people and your race?
When it is completey aligned with india, explain how having good relations with bangladesh in ANY way helps Pakistan? Especially since they are more than 2700 kms away from us.
