Putting conditions like India must not have anything to do with Sri Lanka would make things untenable, he had said.
He said though he was in Colombo to attend a multilateral conference and not for a bilateral engagement, he would have the opportunity on the sidelines of the meet to convey India's views and concerns to the Sri Lankan government on issues like devolving more powers to Tamils and attacks on Indian fishermen in the seas off Sri Lanka.
Prime Minister Singh, who was planning to attend the three-day summit, was last week forced to call off his plans because of competitive politics in Tamil Nadu and fear of isolation of the Congress party in the state ahead of next year's elections.
Against the backdrop of an unanimous resolution passed by Tamil Nadu Assembly demanding a total boycott of CHOGM by India, Mr Khurshid had said he was "perplexed" by the demand.
"We are doing a lot for Tamils of northern areas in Sri Lanka. We are involved in a big project of building 50,000 houses (in war-ravaged areas), laying roads and erecting infrastructure. Nobody is saying you should not be doing this," he said.
After the Congress core group decision that the Prime Minister will not attend the CHOGM meet, Dr Singh had written a letter to Rajapaksa stating his inability to attend the meet.
