Quader, also general secretary of Awami League, said this at a regular press conference at his official residence on parliament premises in the capital.
He said since the outset of Rohingya crisis, Prime Minister Sheikh Hasina has been continuing diplomatic efforts seeking cooperation from the international community for a peaceful solution to the problem.
The economy and environment of Bangladesh have been affected badly for hosting around 12 lakh Rohingyas who took shelter at Ukhia and Teknaf, he added.
The minister said social environment and ecological balance of the areas are now at stake due to excessive number of people living there. It is also putting adverse impacts on the tourism industry centring the world's longest natural sea beach in Cox's Bazar, he said.
