National Defense Ministry's spokesman, Wu Qian, said the country would defend its territorial sovereignty "at all cost" and that Chinese border troops have taken initial counter measures at the site.
"The 90-year history of the Chinese People's Liberation Army (PLA) demonstrated that the army's ability to safeguard the national sovereignty and territorial integrity has continued to strengthen".
"Shaking a mountain is hard", Senior Colonel Wu Qian of the PLA said in a message to India, adding: "Shaking the PLA is even more hard".
The PLA has already carried out two brigade-level exercises, including live-fire exercises, logistics support drills and the testing of a light battle tank, on the Tibetan plateau since the confrontation began mid-June after Beijing claimed Indian troops had stopped the Chinese from constructing a road.
New Delhi also says the road, if built, will have serious security implications for India.
The withdrawal of Indian soldiers was a precondition for resolving the situation, he said.
Beijing has ruled out any talks over the border row until India withdraws troops from Doklam in the Sikkim sector. This is the basis for settling the issue", he said, adding that "peace and security of border areas conforms with the interest of both Chinese and Indian people.
"The determination and will of China to defend its sovereignty is unwavering and indomitable".
Nepal's key political parties should adopt a common position on the standoff and call on both sides to maintain restraint, the parliamentarians said. Chinese state media have also issued warnings in the past two months stating that if the standoff escalates, New Delhi would face a bigger loss than in the 1962 Indo-China war.
Earlier Chinese Foreign Ministry spokesperson Gang said, "China has pointed out many times that the illegal trespass of Indian border troops of the mutually recognised border line is different in nature from the frictions in the undefined sections of the boundary".
Last week, Ms Swaraj said that "both sides must pull back troops to discuss a solution" and told parliament that all other countries back India's action and feel China is trying to bully Bhutan into surrendering a part of its territory.
This dispute is different in nature from the previous frictions happened at undefined boundaries, he added.
