China on Monday asked India to be "cautious" and exercise "restraint" over building infrastructure in Arunachal Pradesh, few days after the Dhola-Sadiya bridge was launched by Prime Minister Narendra Modi.
China claims Arunachal Pradesh as South Tibet. India has repeatedly rejected that stand, asserting that the border state is an integral part of India.
"We hope India adopts a cautious and restrained attitude on the issue before the final settlement of the border issue with China to jointly control disputes, safeguard peace and tranquility in the border areas," the Chinese Foreign Ministry told in an official statement.
"China's position on the eastern section of the Sino-Indian border areas is consistent and clear," a statement in Chinese said.
PM Modi last week opened the country's longest bridge over the Brahmaputra river that connects Assam's easternmost region with Arunachal Pradesh. The 9.2 km Dhola-Sadiya bridge will cut the distance and travel time between Assam and Arunachal Pradesh by 165 km and five hours.
The bridge, built to accommodate tanks, will ensure swift movement of Indian troops in Arunachal Pradesh which will bolster India's defence along the China border.
China and India fought a brief war in 1962 when the Chinese entered Arunachal Pradesh and unilaterally declared a ceasefire after withdrawing to the McMahon Line.
Since then Indian and Chinese troops have had several skirmishes.
