New Delhi, Oct 11 (ANI): Arunachal Pradesh chief minister Nabam Tuki on Friday said that it is very unfortunate that two archers from Arunachal Pradesh were stopped from going to China for a world championship, after the Chinese Embassy issued them stapled visas as a mark that the border state was a 'disputed region'. Talking to mediapersons, he said that Arunachal Pradesh is a part of India and he does not agree with the idea of considering the state as a disputed land.
