Yes last resort no doubt .But joining any block is fast becoming a reality , as you can't stand on two boat ( China and USA ) together at a time.
You see another cold war already started, and in the long run south China sea will be the center of power struggle.
Myanmar will actually work as the Chinese direct route to the bay of Bengal.
And Bangladesh can act as a hedge against India if necessary.
If Bangladesh China and Pakistan are in the same block , then India can never annex any part of Bangladesh , as a force movement in Pakistan border is enough for India to withdraw any force that is advancing to Dhaka . China even don't have to move a muscle aid Bangladesh, as this block is already serving through the military agreement in Pakistan border.
At the same time, if any massive troop India arrange to Pakistan border , we also can arrange troops in Indian Eastern border.
So Pakistan and Bangladesh can help each other and also both nation can focus on economy alongside military.
And China will be protecting its allies in in security council using veto!
So USA block shall not harm us.
And since India will never get out from it's super power delusion , so we can always stay in Chinese block.
Win win situation for all of the members of the block.
India exactly don't want to join us in Chinese block ( look a sanghi is hilariously trying to convince people) , as it will be a serious threat to expansionist sanghiland aka Akhanda Bharat dream.
Because China , Bangladesh Pakistan alliance will literally encircle India and the result will ,India will lost control on NE India, if literally any war break out against Chinese allies.
Also if the block forms , India will no longer remain in the position of dadagiri in Bangladesh.
