"China is gravely concerned over information that India has granted permission to the Dalai to visit Arunachal Pradesh," Chinese Foreign Ministry spokesman Geng Shuang told the media in Beijing.
China claims Arunachal Pradesh as part of Tibet and routinely objects to any visits by top leaders, officials and diplomats to the area.
China had also aired similar concerns in October last year when India granted permission to the Tibetan spiritual leader's visit to Arunachal Pradesh at the invitation of the state government.
China is "strongly opposed" to the visit, Geng said.
"China's position on the eastern section of China-India border dispute is consistent and clear. The Dalai clique has long been engaging in anti-China separatist activities and its record on the border question is not that good," he said.
Geng said China expressed its concern to India through formal channels.
"Under such a background if India invites the Dalai to visit to the mentioned territory, it will cause serious damage to peace and stability of border region and China-India relations," he said.
"We have expressed concerns to the Indian side, urged India to stick to its political commitments and abide by important consensus the two sides have reached on the boundary question, refrain from actions that might complicate the issue, not provide a platform to the Dalai clique and protect the sound and stable development of the Sino-India relations," he said.
Geng's comments came in the backdrop of an interview to the Chinese media by former Chinese Special Representative on boundary dispute Dai Bingguo in which he said the border dispute between the two nations can be resolved if India gives up claim over Tawang in Arunachal Pradesh.
Asked about Dai's comments, Geng said he has not seen the interview.
He said China's principled position on the boundary question with India is to reach an early solution in the fundamental interest of the two countries.
