Itanagar: Chinese troops reportedly entered 12 km inside Indian territory in Arunachal Pradesh sometime in July-August this year. This startling revelation was made by Bharatiya Janata Party (BJP) leader Tapir Gao on Tuesday.

According to Gao, soldiers from the neighbouring country walked at least 12 km on the Indian side in Anrella Valley of the state's Dibang Valley district.

Pictures and videos from the area have now emerged which seem to point towards the alleged transgression. The incident is believed to have happened sometime during the months of July-August.

Andrella Valley falls on the northeastern side of Mipi, which is the last administrative circle of the district.

When contacted, Gao said: “It’s very insulting and sad that the Indian Army had to dismantle their summer camp which was built during a routine patrol and had to return to their base camp.”

“Until unless there is a proper border demarcation, we will face this frequently,” he said.
