National Security Advisor Shivshankar Menon is scheduled to visit Colombo next week to hold talks on a tri-lateral maritime security treaty among India, Sri Lanka and the Maldives, officials said.
Mr Menon's visit to Lanka comes a few days after Sri Lankan President Mahinda Rajapaksa's younger brother Basil Rajapaksa's visit to India.
Basil, the Minister of Economic Development, met External Affairs Minister Salman Khurshid yesterday in New Delhi and expressed his appreciation for the vast number of projects that are being undertaken by India in Lanka especially in the Northern and Eastern provinces.
During the meeting, Mr Khurshid conveyed India's concerns on the 13th amendment and urged Basil not to do anything to dilute its provisions.
As per the 13th amendment that followed the Indo-Sri Lankan Accord of July 1987, Sri Lankan government had agreed to devolve some authority to the provinces.
Apart from Mr Khurshid, Basil held meetings with Mr Menon and the Foreign Secretary.
Mr Menon, who has served in Colombo as the Indian High Commissioner in the past, will visit Lanka at the invitation External Affairs Ministry and will feature several top level engagements, Lankan officials said.
