In a reference to the eastern Ladakh row, Chief of Army Staff Gen MM Naravane on Thursday said the situation along the northern frontier highlighted the nature of threats facing India in preserving its territorial integrity and sovereignty, noting that the "legacy challenges" have only grown in scale and intensity. He said while the Indian Army will continue to prepare and adapt to the future challenges, the more "proximate, real and present dangers" on India's "active borders" cannot be ignored. The Army Chief was addressing a seminar organised by Centre for Land Warfare Studies, a leading military think-tank. For the last nine months, thousands of Indian and Chinese troops have been engaged in a bitter border standoff in eastern Ladakh that created severe strain in overall bilateral ties.
