Nepal sent a diplomatic note through the Ministry of Foreign Affairs to India on Thursday, expressing disagreement with the new political map of India that includes the disputed territory of Kalapani within its borders.

Nilambar Acharya, the ambassador of Nepal to India, confirmed the formal correspondence made by Nepal to India but did not reveal the content of the note.

Sources, however, said that the note expresses Nepal's discontent with the 'inaccurate' political map issued by India on November 2 and asks the Indian government to correct it.

Acharya said there should not have been any dispute between the two countries in the first place, but the disagreements have been created and they should be resolved through dialogue.

"The process has already begun to settle the dispute," Acharya said. "Nepal government and the embassy have launched the initiative."

This is the first time Nepal has formally responded to India regarding the Kalapani issue.

Nepal has been arguing that the territory east of Kali River belongs to Nepal as per the Article 5 of the Sugauli Treaty signed between Nepal and India in 1816.

There have been numerous protests in Nepal after India issued the map.

The Indian side is yet to respond to the diplomatic note. Raveesh Kumar, the spokesperson of the Indian Ministry of External Affairs, refused to comment on the issue.
