New Delhi, Aug. 8 -- India and China have held talks on boundary delimitation, border management and trans-border cooperation, with New Delhi emphasising the need for China to share technical details on upstream projects on trans-border rivers. These issues figured in the 36th meeting of the Working Mechanism for Consultation and Coordination on India-China Border Affairs (WMCC) in New Delhi on Thursday, according to a readout from the external affairs ministry on Friday. The Indian side underlined that maintaining peace and tranquillity in the border areas is "essential for the overall development of bilateral relations". WMCC, which last met in Beijing on May 27, played a crucial role in managing tensions during the military face-off on the Line of Actual Control (LAC) that lasted more than four years and ended when the two sides reached an understanding in October 2024. The two sides "engaged in frank discussions" and reviewed the situation along LAC, the readout said. As a follow up to outcomes of the 24th round of talks between the Special Representatives on the border issue last year, the two sides had "detailed exchanges on issues related to boundary delimitation, border management, mechanism-building and trans-border cooperation". The readout said: "The Indian side reiterated the need for early convening of the next meeting of the Expert Level Mechanism on trans-border rivers and emphasised the importance of sharing technical details on upstream projects." This was a reference to India's concerns about a mega dam being built by China on the upper reaches of the Brahmaputra river. The $137-billion dam on the Yarlung Tsangpo river is expected to produce three times more energy than China's Three Gorges Dam, currently the world's largest. But there are fears that the dam on the eastern rim of the ecologically fragile Tibetan plateau will have severe environmental impacts that can affect millions downstream in India and Bangladesh. Even at the last meeting of the WMCC in May, the Indian side had stressed on an "early meeting" of the Expert Level Mechanism on trans-border rivers. The Indian side has flagged its concerns about the mega dam to China and emphasised the need for transparency and consultations with downstream countries. The Yarlung Tsangpo becomes the Siang when it enters India's Arunachal Pradesh state, and then the Brahmaputra in Assam before flowing into Bangladesh....
