"These are challenging times (everywhere).....we’ll once again prevail together," he said in a video message, shared by the US Embassy on its official Facebook page on Saturday, adding that nations around the world are working together to overcome the situation.
The US ambassador encouraged all to be positive and realistic; and help each other. "Be strong, be kind."
The US Embassy in Dhaka remains open and many staff members, including Ambassador Miller, are practising social distancing by working from home as much as possible.
The ambassador said they continue to support Bangladeshi friends and partners as they work together to combat COVID-19.
The US Department of State and US Embassy in Dhaka are working to arrange a potential third special chartered flight for US citizens and their families who are willing to return to the US.
The flight is not yet authorised or confirmed but they are targeting Monday (April 13) for the departure date, and an arrival the following day at Dulles International Airport in Washington, DC.
If the flight is authorised to depart from Hazrat Shahjalal International Airport, the US Embassy expects this may be the final US government organised flight returning to the United States from Bangladesh during the COVID-19 crisis.
"We urge US citizens who wish to return to the United States take advantage of this opportunity or be prepared to remain in Bangladesh until commercial flights resume," said the Embassy in an updated message.
On April 5, the US Embassy in Dhaka said the voluntary return of the US citizens to their own country by the two chartered flights exemplifies the strong and enduring cooperation, people-to-people ties, and friendship between Bangladesh and the United States.
"While many Americans are staying in Bangladesh, some have decided to return home; the Embassy is committed to helping them do so," said the Embassy in a media note.
The safety and welfare of American citizens in Bangladesh is the US Embassy’s highest priority, it said.
The US Embassy in Dhaka arranged the second chartered flight for several hundred American citizens and their families that left on Sunday.
On March 19, as a result of the global impact of COVID-19, the US Department of State issued a worldwide Travel Advisory urging US citizens to avoid international travel, and for those who live in the United States, to return or prepare to remain overseas for an indefinite period.
