"After the tri-junction in Doklam in the Sikkim sector, this is the most important tri-junction along the Sino-India border."
Military officials said India is also strengthening its surveillance mechanism to keep an eye on Chinese activities along the borders in the strategically sensitive Tibetan region and has even been regularly deploying choppers to carry out recce.
The visit by Gen Rawat, Ajit Doval and Vijay Gokhale was the first such high-level trip from India to Bhutan after the Doklam standoff.
