LEH/NEW DELHI: China has reinforced its position in Daulat Bag Oldi (DBO) sector, 19km deep inside Indian territory, where they are getting regular supplies through trucks.

According to reports sent to the Union home ministry, the Chinese side had adopted agressive posture during patrolling in the DBO sector, where they have picted five tents, and were refusing to end the face-off which has entered the third week.

After the failed Brigadier-level meeting on Tuesday at Chashool, Indian side stepped up vigil in the area through unmanned aerial vehicles (UAVs) while its troops reported that supplies to the Chinese forces were being replenished through a convoy of trucks.

Nearly 40 PLA personnel are stationed in five tents in the area which is 70km south of Burtse of DBO sector and a banner reads "You are in Chinese territory".

In Delhi, Army chief General Bikram Singh briefed the Cabinet committee on security chaired by Prime Minister Manmohan Singh during which he listed various options before the government including using the military aggressively to resolve the issue, official sources said.

During Tuesday's brigadier-level meeting, the Chinese side maintained that DBO was well in their territory and that the Indian side should leave its claim on it.

The Indian side, however, continued to press that this was in violation of the border agreement asking the PLA officials to withdraw from the area.

The Chinese side insisted that India dismantle bunkers constructed along line of actual control (LAC) in Phuktsay and Chumar areas.

The Indian side informed that all developmental works, construction of bunkers and road has been stopped in area and asked the Chinese side for an "unconditional withdrawal of Chinese troops from the Indian territory as per the agreements signed between the two sides on earlier occasions."

The Indian side, during the meeting on Tuesday, had also mentioned the contruction activities on the Chinese side in Phuktsay area. The Chinese side said the issue would be taken up at the higher level and they would revert soon.

Meanwhile, local people in Ladakh area have been found to be resentful towards, what they call, the lenient posture of Indian authorities.
