The Dalai Lama has visited a quiet frontier town in northeast India called Tawang, despite Chinese opposition.
BBC explains how the region is hotly-contested, even though many citizens consider themselves part of India, not China, which technically the land is:
But Tawang - with its proximity to Tibet - has immense strategic value.
China has never recognised India's control over the entire state of Arunachal Pradesh, including Tawang.
It sees it as an extension of Tibet and therefore believes it should be part of China.
China foreign ministry spokesman Qin Gang stated today that the move signaled an "anti-Chinese stance" from the Tibetan spiritual leader and that China "strongly opposes it."
