India–China border infrastructure
Border infrastructure along the Sino-Indian border, which has several border areas disputed by both India and China, encompasses irrigation, roads, railways, airports, natural gas and oil pipelines, electricity grids, telecommunications, and broadcasting. In the context of the border tensions between India and China, many of these infrastructure projects in the borderlands are considered strategic in nature.
