The Congress asked Prime Minister Narendra Modi on Wednesday how much of India's land had been occupied by the Chinese army and what he was doing to remove them from the Indian territory.
Congress spokesperson Manish Tewari said former Army generals and defence experts feared that around 40-60 square kilometres of Indian territory had been "illegally occupied" by China.
Tewari asked Modi who was responsible for it and whether he would fix any responsibility.
"We also want to ask the prime minister about the Chinese intrusion. How did the Chinese soldiers enter India?" Tewari asked at an online press conference.
