Chief Minister Dorjee Khandu said, "Chinese claims over Arunachal Pradesh are simply baseless and not correct. Arunachal Pradesh is an integral part of India and would continue to do so."
In 2003, Beijing gave up its territorial claim over the Indian state of Sikkim but still holds on to its stand that nearly all of Arunachal Pradesh belongs to it.
"The Government of India should be more assertive and make its stand on Arunachal Pradesh very clear to China. New Delhi needs to make a bold statement about frequent Chinese claims," a ruling Congress party MP Takam Sanjay said.
The reaction of Arunachal Pradesh lawmakers comes after allegations of a Chinese intrusions in Ladakh in Jammu Kashmir.
