Ruling CPN has said India undermined Nepal's sovereignty by constructing road to Mansarovar of China through Lipu Lekh.
Issuing a statement signed by chairmen KP Sharma Oli and Pushpa Kamal Dahal late Saturday night, CPN has also deplored India for doing so at a time when the entire humanity is faced with unprecedented health crisis and focused on fighting against the COVID-19 pandemic.
"CPN believes in good neighborly relations between Nepal and India based on the principles of sovereign equality, territorial integrity, mutual respect and benefit," the statement says. "All historical facts and evidences, including the Sugauli Treaty, clearly stipulate that the areas east of Kali (Mahakali) River, including Limpiyadhura, Kalapani and Lipu Lekh are territories of Nepal."
CPN has pointed that the fact was reiterated by Nepal on May 15, 2015 in response to the inclusion of Lipu Lekh Pass as a bilateral trade route without Nepal's consent in the Joint Statement issued during the official visit of the Prime Minister of India to China.
The government earlier on the day expressed regret over India constructing road to Mansarovar through Lipu Lekh.
Issuing a statement, the Ministry of Foreign Affairs also urged India to refrain from carrying out any activity inside the territory of Nepal.
The government has also reiterated commitment to seeking diplomatic solution to boundary issues on the basis of the historical treaty, documents, facts and maps in keeping with the spirit of close and friendly ties between the two countries. "With this in mind, the Government of Nepal has proposed twice the dates for holding the meeting of the Foreign Secretaries of the two countries, as mandated by their leaders, for which the response from the Indian side is still awaited."
