The new Indian line of credit, worth a staggering $4.5 billion, will be used to fund 17 major projects in Bangladesh, which include electricity, railroads, roads, shipping and ports.
"Bangladesh has developed significantly on the socioeconomic front in the past seven years," Jaitley said following the signing of the deal.
"We have stood by Bangladeshs attempts to develop and we will do so in the future. This significant agreement is a continuation of that effort," he said.
Speaking on the occasion, Muhith said, "Bangladesh and India have excellent relations at the moment.
"They stood by us during our independence. We hope they will continue to do so in the future," Muhith was quoted as saying by the bdnews.
The $4.5 billion deal was announced during Prime Minister Sheikh Hasina's visit to India in April. Jaitley's trip to Bangladesh was used to finalise the agreement.
Under the agreement, Bangladesh would have to purchase 65 to 75 per cent of the services, goods or works from the Indian market with the money to be provided under the third LoC following the precedence of the previous two nearly identical agreements.
Bangladesh has two other LoCs open with India: the first one was signed in 2010, and the second one in 2016. These LOCs are collectively worth Tk3.06 billion, but till last year, Bangladesh government has been able to use only $576 million.
Some projects under the first LoC of $862 million faced delay in implementation while the physical works of the 14 projects under the second LoC of $2 billion were yet to start.
