New Delhi, Aug 29 - Sri Lanka will work for stronger ties with India and ensure the quick rehabilitation of Tamils displaced in the military conflict, Colombo's high commissioner Romesh Jayasinghe said after he was named the new foreign secretary.

'The Sri Lankan government stands for the return of internally displaced persons (IDPs) to their homes, the quick completion of the demining process and the rehabilitation of those displaced by the conflict,' Jayasinghe told IANS.

The envoy, who takes over as foreign secretary Oct 1, thanked India for its support for Colombo's efforts to rehabilitate the nearly 300,000 Tamil civilians living in camps after the Tamil Tigers were crushed in May.

'We are confident that with India's support we will be able to achieve our target,' he said when asked about the six-month deadline set by Colombo to resettle displaced Tamils in their original homes.

Jayasinghe will succeed Palitha Kohona, the current foreign secretary who has been appointed Sri Lanka's Permanent Representative to the UN in New York.

An additional secretary of the foreign ministry, Prasad Kariyawasam, who was Permanent Representative to the UN in New York, will succeed Jayasinghe as the envoy in New Delhi.
