evidence: Official sources said about 35 PLA men returned to Chumar in northeast Ladakh and were perched on a hillock claiming the area to be part of China while another 300 soldiers were maintaining presence close to Line of Actual Control. [...] Chumar, the last village in Ladakh area bordering Himachal Pradesh, has been a bone of contention with China claiming it to be its own territory and has been frequenting the area with helicopter incursions almost every year. Chumar had become a flash point during the fortnight long standoff last year in Daulat Beg Oldie as the Chinese side had objected to overhead bunkers erected by the Indian side.
