Amid keenness on both sides to expedite resolution of the boundary dispute, special representatives of India and China on Wednesday held detailed discussions on the vexed issue that has been nagging relations for decades.

At the two-day talks, which will conclude on Thursday, the Indian side is represented by National Security Adviser M K Narayanan while the Chinese side is represented by Dai Bingguo.

The discussions went well, and the two sides discussed how the differences can be narrowed down, sources said.

The two sides are understood to have deliberated on the delineation of the Line of Actual Control on their respective maps.

The ninth round of talks between special representatives comes about two months after Chinese President Hu Jintao's visit to New Delhi during which the two sides underlined that early settlement of the dispute would be beneficial for both countries.

"An early settlement of the boundary question will advance the basic interests of the two countries and shall, therefore, be pursued as a strategic objective," a Joint Declaration issued during Hu's visit had said.

It said the special representatives shall complete at an early date the task of finalising an appropriate framework for a final package settlement covering all sectors of the India-China boundary.
