"It's totally outrageous and unfortunate that we turned down help, which could have only helped," said Naushad Hussain, a Bangladeshi citizen living in Kuala Lumpur.
Shammi Huda, a businessman in Dhaka, said his reaction to the news was one of "complete and utter disgust."
"Dhaka is always rife with conspiracy theories at best of times, but common sentiment is that government wanted to avoid any possibility of disputes arising over death tolls or competence in handling the situation," he said. "And that would have arisen with independent international observers and experts at hand."
At the site of the collapse, the recovery effort continued Tuesday, as yellow cranes sifted through concrete slabs.
For six days, rescuers had done all they could, many of them clawing with their bare hands through metal and rubble to reach survivors. They pulled out more than 2,400 alive.
