"They had a very fruitful and constructive visit...This delegation served a very useful purpose of conveying the entire country's concerns about the problems Tamil speaking Sri Lankan citizens in the country are facing and it has served a very useful purpose," Krishna told reporters outside Parliament House.
He said the government has gone through the report about the visit of the delegation led by Leader of the Opposition in the Lok Sabha Sushma Swaraj.
"We heard a report about their visit, their impressions, their perceptions about what needs to be done," he said, adding the delegation leaders held discussions with President Mahinda Rajapaksa and other leaders from government as well as from other opposition parties and Tamil organisations.
The minister said Sri Lanka is one of the closest neighbours of India with whom it shares historical and civilisational contacts.
