Bank president Jim Yong Kim, on his first visit to the former pariah state, said half of the funds would be used to expand power supplies, in a country where more than 70 per cent of the population does not have access to reliable electricity.
"We are increasing our support for the huge reform effort underway in Myanmar because we want to help the government bring benefits to poor people even more quickly," Kim said in a statement.
The programme also includes USD 200 million to help Myanmar achieve universal health coverage by 2030, the Bank said, noting that only one in four people in the once-isolated country has access to quality healthcare.
The Washington-based institution closed its Yangon office in 1987 and ceased new lending after the then-ruling junta stopped making payments on debts worth hundreds of millions of dollars left from previous programmes.
