Hasina regretted not being able to attend the programme in person due to the coronavirus outbreak.
“It [video conferencing] has been possible because a ‘Digital Bangladesh’ has been established,” the prime minister said.

Joy, often dubbed the man who implemented Hasina’s ‘Digital Bangladesh’ dream, has been advising her on ICT affairs since 2009.
