- China's statement comes after Defence Minister's maiden visit to Nathu La
- Ms Sitharaman's trip was the first high level visit after Doklam standoff
- Nathu La is the last post separating India's Sikkim and Tibet in China
Reacting to Ms Sitharaman's visit to the area, the Chinese foreign ministry today said "the Sikkim section of the China-India border has been demarcated by the historical boundary".
"It is the best testimony to this fact. We urge the Indian side to face the facts, abide by the provisions of the historic boundary treaty and the relevant agreement of the parties, and work together with the Chinese side to maintain peace and tranquillity in the border areas," it said in a written response to PTI, to a query about Ms Sitharaman's visit.
The ministry did not directly name the 1890 Britain-China treaty which Beijing often referred to during the Doklam standoff stating that it has defined the Sikkim section of the boundary with Tibet, therefore the border in that area has been settled.
Ms Sitharaman yesterday visited the Nathu La area on the Sino-Indian border and interacted with Army and Indo-Tibetan Border Police officials.
Ms Sitharaman undertook an aerial survey of the Doklam-Nathu La area, a day after the government said no new developments have come up since India and China disengaged their troops, ending the standoff.
The Defence Minister's trip was the first high level visit to the area after the 73-day standoff between Indian and Chinese troops at Doklam in the Sikkim sector of the border which ended on August 28 following a mutual agreement between India and China.
Of the 3,488-km India-China border which stretches from Jammu and Kashmir to Arunachal Pradesh, a 220-km section falls in Sikkim. The two sides have so far held 19 rounds of Special Representatives' talks to resolve the dispute.
The Doklam standoff began on June 16 over the PLA's plans to build a road in the area claimed by Bhutan after which Indian troops intervened to stop the construction as it posed a security risk to the 'Chicken's Neck' - the narrow corridor connecting India with its northeastern states.
China, which earlier opened the Nathu La route for Indian pilgrims to visit Kailash and Manasarovar, closed it after the Dokalam standoff and is yet to reopen it.
