Bangladesh first and foremost necessity is to preserve Bangladesh sovereignty and independence from indian attack. Now, if Bangladeshis need help from US or Chinese or both, we should be seeking that. Lately though, indians tried to poison Chinese understanding by propagating a lie that Bangladesh will be used against China by US. But that indian lie is to save indian stooges (Awami League regime) which is not only undermining Bangladesh sovereignty, but also undermining Chinese and US interest in Bangladesh.
Furthermore, india, by undermining Bangladesh sovereignty and keeping indian subservient regime only doing long term damage to Chinese interest in disputed area around Tibet. If China fall for indian lie, it will only enable india to use Bangladesh at staging ground and corridor, in future conflict against China.
China also should not fooled by increasing purchase of military equipments by indian subservient current Bangladesh regime. When indian end game is to use Bangladesh defense force as auxiliary in future conflict against China, such purchase is just india orchestrated deception.
Bangladesh played and will play moderation role when it comes to China and US interests. For Chinese they should not forget, it was Bangladeshi origin (then) Pakistani diplomat who played crucial role in establishing diplomatic relation between China and United States. In Bangladesh, for China and US, it is not zero some game as indians are lying to their teeth. Perhaps, Chinese PM (to be more specific) and foreign ministry needs some soul searching before falling for indian lie.
