He said the COVAX programme has not mentioned the source of this supply of AstraZeneca vaccine doses to Bangladesh.
The AstraZeneca vaccine doses will arrive soon, Momen said.
Bangladesh ambassador to the US conveyed the development to the foreign minister.
Bangladesh, earlier sought 2 million doses of AstraZeneca vaccine doses from the US for addressing Bangladesh's immediate needs but the US is yet to reply on that particular request.
On 3 June, the White House announced its plan to share vaccines directly with Bangladesh as part of a framework to provide 80 million US vaccine doses globally by the end of the month. This includes 7 million doses destined for Asia.
