China on Tuesday said there was no scope for a ''compromise'' in the military stand-off with India in the Sikkim area, and put the onus on New Delhi to resolve the ''grave'' situation.
In blunt remarks, China's Ambassador to India Luo Zhaohui said ''The ball is in India's court'' and it was for the Indian government to decide on options to resolve the stand-off.
Asked about remarks by official Chinese media and think-tanks that the conflict can lead to a ''war'' if not handled properly, the ambassador said in an interview to PTI, ''There has been talk about this option, that option. It is up to your government policy (whether to exercise military option).''
He said withdrawal of Indian troops from the area is a ''pre-condition'' for a peaceful resolution, and there is no scope for a ''compromise'' on the issue.
''The first priority is that the Indian troops unconditionally pull back to the Indian side of the boundary. That is the precondition for any meaningful dialogue between China and India,'' he said.
China and India have been engaged in a stand-off in and area near the trijunction with Bhutan, variously labelled 'Doklam' and 'Doka La', for past 19 days after Indian troops reportedly prevented a Chinese army construction party from building a road.
Doka La is the Indian name for the region which Bhutan recognises as Doklam, while China claims it as part of its Donglang region. China and Bhutan are engaged in talks over the resolution of territorial claims. Bhutan, however, has no diplomatic ties with China and it is supported militarily and diplomatically by India.
''The situation is grave and made me deeply worried. It is the first time that Indian troops have crossed the mutually recognised boundary and trespassed into China's territory, triggering a close range face-off between Chinese and Indian border troops. Now, 19 days have passed but the situation still has not eased,'' Luo said.
He also asserted India has no right to interfere in the China-Bhutan boundary talks, nor is it entitled to make territorial claims on behalf of Bhutan.
The Indian ministry of external affairs had said India was ''deeply concerned at the recent Chinese actions and had conveyed to the Chinese government that such construction would represent a significant change of status quo with serious security implications for India''.
''As for the so called 'security concerns' of the Indian side, India has crossed a delimited boundary into another country's territory in the name of security concerns, which will not be acceptable to any sovereign state. India cannot encroach upon the territory of other countries on the ground of its 'security concerns'. Otherwise, the world would be in chaos,'' the Chinese envoy said.
He also asserted ''it is critical that India shall withdraw its troops immediately to minimise the negative impact. It serves the interests of the two sides.''
He also noted the current stand-off was of different nature from the previous frictions between the two countries, and said it was the first time that such a severe situation had occurred at the Sikkim section of the China-India boundary.
