During the course of the intense and complex negotiations between senior commanders of the two armies that ended at 2 am on Wednesday, the Indian delegation also apprised the Chinese PLA about the "red lines" and conveyed that the onus was largely on China to improve the overall situation in the region, the sources said.
His remarks came days after Beijing raised eyebrows over India testing 5000 km-range Agni 5 missile which has entire China within its reach.
China has reacted cautiously to India's proposal for the establishment of mountain strike corps along the Sino-Indian border, while the official media in Beijing ignored the development.
"I still have not heard a credible explanation as to why they chose to bring that size of forces to that sector of our border. Now, if peace and tranquility is disturbed and attempts are being made to change the LAC status quo unilaterally and large forces are brought to the border in contravention of written agreements, then obviously the relationship will be impacted," he said.
In a strong response to China's objection to development of infrastructure on the Indian side of the LAC, New Delhi also asserted that Beijing has no locus standi to comment on India's internal matters.
Singh said a meeting between senior Indian and Chinese military leaders has been scheduled for June 6 even as he asserted that India is not going to back off from its position. Asked about the current situation in sensitive areas in eastern Ladakh, he said Chinese have come up to what they claim is their territory while Indians believed it is theirs.
Gen Naravane said that the Indian Army did not hide casualties during Galwan clash in eastern Ladakh as the Chinse have done.
Army Spokesperson Colonel Aman Anand said troops from China's People's Liberation Army (PLA) 'violated' the consensus arrived at during military and diplomatic engagements on the ongoing standoff in eastern Ladakh, and carried out provocative military movements to change the status quo.
On the first anniversary of the deadly clashes, the army said the supreme sacrifice of the soldiers while fighting the adversary in the "most difficult" high altitude terrain will be "eternally etched" in the memory of the nation.
The Army Chief further spoke about the situation at other friction points where China was aggressive like Gogra Hotsprings.
China on Tuesday announced that its Defence Minister General Li Shangfu will visit India this week to attend the meeting of SCO defence ministers from April 27 during which he is expected to hold talks with his Indian counterpart Rajnath Singh on ending the prolonged eastern Ladakh standoff which has severely strained bilateral ties.
The Indian side is expected to seek disengagement as soon as possible in the remaining friction points besides pressing for resolution of issues in Depsang Bulge and Demchok.
'The Modi government is trying to suppress the matter only to save its political image'
The Indian side forcefully pressed for early resolution of the standoff and particularly insisted on expeditious disengagement in Hot Springs and Gogra, a source said.
'India's behaviour violated agreements...It's a serious military provocation'
Many of them sustained minor injuries in the clash near Naku La in the Sikkim sector along the Sino-Indo border on Saturday
The Ministry of External Affairs (MEA) spokesperson Anurag Srivastava said complete disengagement requires re-deployment of troops by each side towards their regular posts on their respective sides of the Line of Actual Control(LAC) and this can be done only through mutually agreed actions.
"So, there was no infiltration of any Afghani Taliban... To that effect, we have been able to control (things)," he said.
The Army said it was also highlighted that completion of disengagement in other areas would pave the way for the two sides to consider de-escalation of forces and ensure full restoration of peace and tranquillity and enable progress in bilateral relations.
'The India-China relationship has deteriorated greatly over these past two years and it is set to deteriorate further.'
Jaishankar said the last few years have been a "period of serious challenge", both for the relationship and for the prospects of Asia, noting that continuation of the current impasse will not benefit either India or China.
The only way to resolve the current military standoff along the Line of Actual Control in eastern Ladakh was for Beijing to realise that trying to 'change the status quo by resorting to force or coercion, is not the right way forward', India's ambassador to China Vikram Misri said in a hard-hitting interview to PTI.
China on Monday said Defence Minister A K Antony's visit Beijing has given both countries an opportunity to enhance their "strategic cooperative partnership" and jointly maintain peace and tranquillity in the border areas through increased military-to-military coordination.
The two sides are also expected to finalise a roadmap for restoration of peace and tranquility in the high-altitude region that witnessed an eight-week bitter standoff between the troops of the two countries.
The high-level talks came a week after 20 Indian Army personnel were killed in a violent clash between the two sides in Galwan Valley.
The talks took place over video call on Sunday. According to sources, talks were held for over two hours in a cordial and forward-looking manner.
The armies are working to schedule their seventh round of talks to take steps towards "early and complete" disengagement of troops along the LAC in eastern Ladakh.
'Everytime the Chinese raised the issue of our patrol crossing the line, I told them let's not fight over a line that does not exist yet.' 'Commanders resolved such situations sitting across the table, sometimes we posed veiled threats about creating problems elsewhere along the 800 km frontier as a tit-for-tat.'
The Army Chief was in Ladakh on a two-day visit from June 23 to take stock of the situation.
India has realised that one can only deal with China from a position of strength and that is not palatable to Beijing, observes Dr Rup Narayan Das.
The clear assertion by New Delhi came ahead of a fresh round of Lt General-level talks between the Indian army and the Chinese PLA which government sources said is set to take place within the next two days.
The Chinese military has already completed moving back its troops from the face-off sites in Galwan Valley, Gogra and Hot Springs in line with the first phase of the disengagement process from the friction points on the LAC in eastern Ladakh, sources said. The main focus now shifts to Pangong Tso. India has been insisting that China must withdraw its forces from areas between Finger Four and Eight.
The Indian Army on Friday strongly insisted on early disengagement of troops by China from all the friction points in eastern Ladakh at the eighth round of corps commander-level talks between the two sides that primarily focused on a roadmap for restoration of peace and tranquillity in the region, according to people familiar with the developments.
China said it was committed to peace and tranquility at the border areas.
The meeting will take place in Chushul sector on the Indian side of Line of Actual Control.
'It is because of the bravery of Colonel Santosh Babu and his men that we have not seen a violent escalation anywhere else along the LAC.'
Raking up the border issue, Congress leader Rahul Gandhi on Friday said every individual in Ladakh knows that China has "taken away our land" and claimed that Prime Minister Narendra Modi's assertion that not an inch of land was taken away was "absolutely false".
Making a statement in Lok Sabha, Singh also said the Indian Army has inflicted heavy costs including casualties on the Chinese side during the clash with the People's Liberation Army at the Galwan valley on June 15.
Gen Naravane reviewed the overall security situation in the region with Northern Army Commander Lt Gen Yogesh Kumar Joshi, commander of the 14 Corps Lt Gen Harinder Singh and other senior Army officials.
The next phase of the de-escalation process will kick off only after the fourth round of talks between corps commanders of the two sides.
