Document 12: 2008 Summer Olympics torch relay: Thailand: The April 18 relay through Bangkok was the Olympic flame's first visit to Thailand. The relay covered just over 10 km, and included Bangkok's Chinatown. The torch was carried past Democracy Monument, Chitralada Palace and a number of other city landmarks. M.R. Narisa Chakrabongse, Green World Foundation (GWF) chairwoman, withdrew from the torch-running ceremony, protesting against China's actions in Tibet. Several hundred protesters were present, along with Olympic supporters. Thai authorities threatened to arrest foreign protesters and ban them from future entry into Thailand. A coalition of Thai human rights groups announced that it would organise a "small demonstration" during the relay, and several hundred people did indeed take part in protests, facing Beijing supporters. Intended torchbearer Mom Rajawongse Narissara Chakrabongse boycotted the relay, to protest against China's actions in Tibet.

Document 13: 2008 Summer Olympics torch relay: India: Due to concerns about pro-Tibet protests, the relay through New Delhi on April 17 was cut to just 2.3 km (less than 1.5 miles), which was shared amongst 70 runners. It concluded at the India Gate. The event was peaceful due to the public not being allowed at the relay. A total of five intended torchbearers -Kiran Bedi, Soha Ali Khan, Sachin Tendulkar, Bhaichung Bhutia and Sunil Gavaskar- withdrew from the event, citing "personal reasons", or, in Bhutia's case, explicitly wishing to "stand by the people of Tibet and their struggle" and protest against the PRC "crackdown" in Tibet. Indian national football captain, Baichung Bhutia refused to take part in the Indian leg of the torch relay, citing concerns over Tibet. Bhutia, who is Sikkimese, is the first athlete to refuse to run with the torch. Indian film star Aamir Khan states on his personal blog that the "Olympic Games do not belong to China" and confirms taking part in the torch relay "with a prayer in his heart for the people of Tibet, and ... for all people across the world who are victims of human rights violations". Rahul Gandhi, son of the Congress President Sonia Gandhi and scion of the Nehru-Gandhi family, also refused to carry the torch.
Document 14: 2008 Summer Olympics torch relay: India rejected Chinese demands that the torch route be clear of India's 150,000-strong Tibetan exile community, by which they required a ban on congregation near the curtailed 3 km route. In response Indian officials said India was a democracy, and "a wholesale ban on protests was out of the question". Contradicting some other reports, Indian officials also refused permission to the "Olympic Holy Flame Protection Unit". The combined effect is a "rapid deterioration" of relations between India and China. Meanwhile, the Tibetan government in exile, which is based in India, has stated that it did not support the disruption of the Olympic torch relay.
Document 15: 2008 Summer Olympics torch relay: Wary of protests, the Indian authorities have decided to shorten the route of the relay in New Delhi, and have given it the security normally associated with Republic Day celebrations, which are considered terrorist targets. Chinese intelligence's expectations of points on the relay route that would be particularly 'vulnerable' to protesters were presented to the Indian ambassador to Beijing, Nirupama Sen. The Indian media responded angrily to the news that the ambassador, a distinguished lady diplomat, was summoned to the Foreign Ministry at 2 am local time; the news was later denied by anonymous sources in Delhi. The Indian media reported that India's Commerce Minister, Kamal Nath, cancelled an official trip to Beijing in protest, though both Nath and Chinese sources have denied it.
