China admonished the United States on Monday for sending its ambassador in India to a contested stretch of land on the India-China border, warning that a third party's meddling would only complicate the dispute between Beijing and New Delhi.
China claims more than 90,000 sq. km of territory disputed by India in the eastern sector of the Himalayas. Much of that forms the Indian state of Arunachal Pradesh, which China calls South Tibet.
U.S. Ambassador to India Richard Verma posted photos on his Twitter account Friday of his recent trip to Arunachal Pradesh, thanking Indian officials for their "warm hospitality" and calling the region a "magical place."
