As tensions around Taiwan draw renewed international attention, Washington’s ongoing support for Taipei might not be Beijing’s only reason for concern.

The U.S. military is planning to hold high-altitude ground training with India less than 100 kilometers away from the South Asian country’s disputed border with China — which would put the exercises closer to Chinese territory than ever before. The timing and location of the drills, analysts say, are intended to send a strong message to the Chinese Communist Party.

The mountaintop drills are set to take place from Oct. 18 to 31 in the Himalayas amid high tensions along the Line of Actual Control, the 4,057 km de facto border between the two countries that stretches across several northern Indian states.
