China, which is already miffed with India's re-activation of advanced landing grounds at Daulat Beg Oldi, Fukche and Nyoma and building of other infrastructure along the LAC over the last four-five years, is uncomfortable with Indian being able to peep at the movement on the highway. The Chinese, in fact, have frequently tried to "immobilize'' the surveillance cameras positioned at the Chumar post by cutting wires.
Last year, Indian troops had intercepted two Chinese personnel on mules across the Chumar post. Though they were subsequently let off, with language being a barrier, China got hugely irritated about the incident. Holding that the two Chinese were from its revenue department, Beijing since then has been pressing hard for the Chumar post to be dismantled.
