Also if you carefully look at the geopolitics, you see that China has only access to Eastern water, and with rest of the world China has access through malacca strait only which is the chicken neck for China ( ad shiliguri corridor for India) , and in ww2 China faced hostile naval blockade from Japan.
That time usa and West was their ally and they used Indian route to supply China, so China remain alive.
Now when they are adversary of China , so now if USA impose naval blockade on malacca strait ( usa can use andaman as base ) , China will literally come down on it's knees in few weeks.
As Pakistan isn't a good access to Arabian sea through karakoram highway.
So only Myanmar is the direct route for China to access the bay of Bengal.
So why on earthly reason China will go against Myanmar?
China can survive without the gas of Myanmar I think as Russia can give them gas ( I could be wrong here though) , but without access to the bay of Bengal, China can't survive as only a 40 km malacca strait is their only way to trade with rest of the world that can easily be blocked with a hostile navy.
And usa has the far more advanced navy than any other countries in the world.
So why China will entertain Bangladesh by digging their own grave? No reason!
The problem of our people is we consider ourselves superior to others. একে বলে গাঁয়ে মানে না, আপনি মোড়ল!
This mentality never bring a good result in the end. The world doesn't revolve around the so called superiority of muktizuddher chetona, that is now mostly use it business purpose!
