Chinese Ambassador Luo Zhaohui on Tuesday urged India to unconditionally withdraw its border troops to the Indian side of the boundary with China and seek a peaceful solution to the recent incident in the Doklam area.
In an interview with the Press Trust of India (PTI) news agency, Ambassador Luo said he was deeply worried by the "grave" situation in Doklam.
"It is the first time that the Indian troops have crossed the mutually recognized 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," he said.
"It is the first time that such a severe situation has occurred at the Sikkim section of the China-India boundary. This section has already been delimited with clear alignment of the boundary, the two sides have consensus on it and there has been no incident over the past years," the ambassador added.
According to Ambassador Luo, the Convention between Great Britain and China Relating to Sikkim and Tibet (1890) explicitly stipulates that Doklam undoubtedly belongs to China's territory. After independence, India inherited this historical convention and successive Indian governments have repeatedly confirmed that in written forms, recognizing that it concurs with China on the boundary alignment at the Sikkim section.
The Chinese diplomat expounded on China's three-point position on the situation in Doklam.
"The first one 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.
The second one is to seek a peaceful solution, according to the ambassador.
"China attaches great importance to the China-India relations and is ready to develop a long-term stable strategic partnership for cooperation with India. The current level of cooperation and friendship between China and India are hard earned and deserve to be cherished by the two sides," said Ambassador Luo.
He added that the third one is to maintain peace and tranquility in the border areas.
"China has always taken this seriously and done a lot to this end. It needs joint efforts of the two sides. We appreciate what Prime Minister (Narendra) Modi said in St. Petersburg that over the past 50 years, not a single bullet has been fired at the India-China border areas."
The ambassador stressed that the three top priorities are connected with each other. "Only by fulfilling the unconditional withdrawal of India's military, can peaceful resolution of this issue be achieved. Only by approaching with peaceful resolution, can peace and tranquility of the border areas be maintained."
Stressing the fact that Doklam belongs to China and has long been under the effective jurisdiction of China, Ambassador Luo said "now the ball is in the court of the Indian side."
The Chinese envoy also dismissed the Indian side's views on the border incident as self-contradictory. "On the one hand, India claims that Doklam belongs to Bhutan. On the other hand, it denies the 1890 Convention and claims that the Sikkim section of the China-India boundary is not delimited and uses it as a pretext for its trespassing into China's territory."
Despite the incident, the ambassador said he was always optimistic about the China-India relations.
Noting that the two countries are neighboring powers as well as members of BRICS and the Shanghai Cooperation Organization, he hoped both sides should focus on cooperation, well manage such existing problems as the boundary issue, uphold a positive attitude to address emerging issues of the bilateral ties and set a vision for the China-India relations.
