I think Bangladesh can persuade Russia to take a neutral position in UN if vigorous diplomatic initiative is undertaken.Russia is a far away country.It has only business interest in myanmar unlike China which is a direct neighbor and have geo-political and economic interest.Russia also have large business interest in Bangladesh.They are building 12 billion dollar nuclear power plant in Bangladesh as well as supplying billions of dollar worth arms.Russian hydrocarbon giant Gazprom is also present in BD.Russia's geo-political interest mainly lies in Baltic, Black sea, Arctic and northen Pacific.Not in Bay of Bengal or Indian ocean unlike China.But for China, making them neutral is an uphill battle task for Bangladesh nearing impossible in current scenario.
