With tensions rising between China and India, New Delhi has deployed nearly 100 tanks to its eastern border.

The mountainous region of Ladakh, in northern India, lies in a tense location between disputed Kashmir and Tibet. In an effort to boost its military presence in the area, the Indian military has sent Russian-made T-72 tanks to Ladakh’s Chinese border.

"The vast flat valleys along the mountain ranges allow for armored movement; besides, there has been an increase in the force levels across the border," an unnamed military official told NDTV.

The tanks have undergone significant upgrades to be better outfitted for the region’s climate.

"We have procured special additives and lubricants for high-altitude terrain such as winter-grade diesel and additives for the lubrication system, which prevents it from freezing in the tank," Colonel Vijay Dalal told The Hindu.

This marks the third regiment placed in Ladakh by India since 2014.

Tensions between the neighbors have been building recently. Earlier this month, the Indian Navy deployed three ships to the South China Sea.

"The visiting ships are also likely to conduct exercises with the Royal Malaysian Navy aimed at enhancing interoperability in communication as well as Search and Rescue procedures," said a statement issued by India’s Defense Ministry.

Malaysia is currently at odds with China over territorial claims in the waterway.

Beijing and New Delhi are also competing over Nepal. While Nepalese Prime Minister Khadga Prasad Sharma Oli has expressed an interest in working more closely with the Chinese government, India is unlikely to surrender its own influence over Kathmandu.
