The Indian foreign ministry acknowledged, for the first time on Thursday, that the military had sent troops to the border, accusing China of causing the tensions by starting military deployments.
The two sides keep blaming each other for this month’s deadly fighting during which 20 Indian soldiers were killed.
The fighting, the deadliest since 1967, occurred in the border area that lies between China’s Tibet and India’s Ladakh regions.
India’s foreign ministry spokesman, Anurag Srivastava, said on Thursday that "both sides remain deployed in large numbers in the region, while military and diplomatic contacts are continuing.”
He blamed "Chinese actions" on the unofficial border, known as the Line of Actual Control (LAC), for this month's deadly fight with rocks and batons. No shots were fired.
"At the heart of the matter is that since early May, the Chinese side has been amassing a large contingent of troops and armaments along the LAC," he said.
Srivastava also accused Chinese forces of building "structures" on the Indian side of their demarcation line in the Galwan Valley in Ladakh.
"While there have been occasional departures in the past, the conduct of Chinese forces this year has been in complete disregard of all mutually agreed norms," the spokesman said.
He warned that a “continuation of the current situation would only vitiate the atmosphere for the development of the relationship."
