India on Tuesday rejected China's claim that Arunachal Pradesh was Chinese territory.

"Arunachal is an integral part of India," External Affairs Minister Pranab Mukherjee told reporters in New Delhi, a day after Chinese Ambassador Sun Yuxi claimed that the east Indian state was "Chinese territory".

The Chinese Ambassador had told CNN-IBN, "In our position, the whole of Arunachal Pradesh is Chinese territory and Tawang is only one place in it. We are claiming whole of that (Arunachal Pradesh). That is our position."

India and China are currently engaged in talks to resolve the boundary question. Last year, they signed the 'Political Parameters and Guiding Principles' to resolve the border issue.

Arunachal Pradesh Governor S K Singh, himself a former diplomat who retired as foreign secretary, also disapproved of the Chinese ambassador's comments saying it was an "arrogant" way of negotiation.

"This is an arrogant way of negotiation from China. The Chinese have done this before, it is an odd way," he said.
