From pushing in small arms over a decade ago in Kashmir, the Sino-Pakistan defence partnership has morphed into a considerable military alliance in the last few years. Last week’s military exchanges between the two arch-rivals offered glimpses of this friendship between two `iron clad’ allies.

In a big reveal, the Government of India on Wednesday, said that the Indian Air Force had successfully jammed Chinese air defence systems that Pakistan had installed all along its border and Line of Control with India.

Increasing Western military support to India, and China’s to Pakistan, signals a shift in global alignments — and another potential flashpoint for international tensions.
