Question: How many supporters of the region that traded horses with Ming were expected in Canberra to protest?

full_context: Document 1: Sino-Tibetan relations during the Ming dynasty: Meanwhile, the Tumed Mongols began moving into the Kokonor region (modern Qinghai), raiding the Ming Chinese frontier and even as far as the suburbs of Beijing under Altan Khan (1507–1582). Klieger writes that Altan Khan's presence in the west effectively reduced Ming influence and contact with Tibet. After Altan Khan made peace with the Ming dynasty in 1571, he invited the third hierarch of the Gelug—Sönam Gyatso (1543–1588)—to meet him in Amdo (modern Qinghai) in 1578, where he accidentally bestowed him and his two predecessors with the title of Dalai Lama—"Ocean Teacher". The full title was "Dalai Lama Vajradhara", "Vajradhara" meaning "Holder of the Thunderbolt" in Sanskrit. Victoria Huckenpahler notes that Vajradhara is considered by Buddhists to be the primordial Buddha of limitless and all-pervasive beneficial qualities, a being that "represents the ultimate aspect of enlightenment." Goldstein writes that Sönam Gyatso also enhanced Altan Khan's standing by granting him the title "king of religion, majestic purity". Rawski writes that the Dalai Lama officially recognized Altan Khan as the "Protector of the Faith".
Document 2: 2008 Summer Olympics torch relay: Australia: The event was held in Canberra, Australian Capital Territory on April 24, and covered around 16 km of Canberra's central areas, from Reconciliation Place to Commonwealth Park. Upon its arrival in Canberra, the Olympic flame was presented by Chinese officials to local Aboriginal elder Agnes Shea, of the Ngunnawal people. She, in turn, offered them a message stick, as a gift of peace and welcome. Hundreds of pro-Tibet protesters and thousands of Chinese students reportedly attended. Demonstrators and counter-demonstrators were kept apart by the Australian Federal Police. Preparations for the event were marred by a disagreement over the role of the Chinese flame attendants, with Australian and Chinese officials arguing publicly over their function and prerogatives during a press conference.
Document 3: Sino-Tibetan relations during the Ming dynasty: Discussions of strategy in the mid Ming dynasty focused primarily on recovery of the Ordos region, which the Mongols used as a rallying base to stage raids into Ming China. Norbu states that the Ming dynasty, preoccupied with the Mongol threat to the north, could not spare additional armed forces to enforce or back up their claim of sovereignty over Tibet; instead, they relied on "Confucian instruments of tribute relations" of heaping unlimited number of titles and gifts on Tibetan lamas through acts of diplomacy. Sperling states that the delicate relationship between the Ming and Tibet was "the last time a united China had to deal with an independent Tibet," that there was a potential for armed conflict at their borders, and that the ultimate goal of Ming foreign policy with Tibet was not subjugation but "avoidance of any kind of Tibetan threat." P. Christiaan Klieger argues that the Ming court's patronage of high Tibetan lamas "was designed to help stabilize border regions and protect trade routes."
Document 4: 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. In Bangkok, students told the media that the Chinese Embassy provided them with transportation and gave them shirts to wear.
Document 5: 2008 Summer Olympics torch relay: A Macau resident was arrested on April 26 for posting a message on cyberctm.com encouraging people to disrupt the relay. Both orchidbbs.com and cyberctm.com Internet forums were shut down from May 2 to 4. This fueled speculation that the shutdowns were targeting speeches against the relay. The head of the Bureau of Telecommunications Regulation has denied that the shutdowns of the websites were politically motivated. About 2,200 police were deployed on the streets, there were no interruptions.
Document 6: 2008 Summer Olympics torch relay: Hong Kong: The event was held in Hong Kong on May 2. In the ceremony held at the Hong Kong Cultural Centre in Tsim Sha Tsui, Chief Executive Donald Tsang handed the torch to the first torchbearer, Olympic medalist Lee Lai Shan. The torch relay then traveled through Nathan Road, Lantau Link, Sha Tin (crossed Shing Mun River via a dragon boat, which had been never used before in the history of Olympic torch relays), Victoria Harbour (crossed by Tin Hau, a VIP vessel managed by the Marine Department) before ending in Golden Bauhinia Square in Wan Chai. A total of 120 torchbearers were selected to participate in the event consisting of celebrities, athletes and pro-Beijing camp politicians. No politicians from the pro-democracy camp were selected as torchbearers. One torchbearer could not participate due to flight delay. It was estimated that more than 200,000 spectators came out and watched the relay. Many enthusiastic supporters wore red shirts and waved large Chinese flags. According to Hong Kong Chief Secretary for Administration Henry Tang, 3,000 police were deployed to ensure order.
Document 7: Sino-Tibetan relations during the Ming dynasty: Laird writes that the Ming appointed titles to eastern Tibetan princes, and that "these alliances with eastern Tibetan principalities are the evidence China now produces for its assertion that the Ming ruled Tibet," despite the fact that the Ming did not send an army to replace the Mongols after they left Tibet. Yiu Yung-chin states that the furthest western extent of the Ming dynasty's territory was Gansu, Sichuan, and Yunnan while "the Ming did not possess Tibet."
Document 8: Sino-Tibetan relations during the Ming dynasty: Tsai writes that shortly after the visit by Deshin Shekpa, the Yongle Emperor ordered the construction of a road and of trading posts in the upper reaches of the Yangzi and Mekong Rivers in order to facilitate trade with Tibet in tea, horses, and salt. The trade route passed through Sichuan and crossed Shangri-La County in Yunnan. Wang and Nyima assert that this "tribute-related trade" of the Ming exchanging Chinese tea for Tibetan horses—while granting Tibetan envoys and Tibetan merchants explicit permission to trade with Han Chinese merchants—"furthered the rule of the Ming dynasty court over Tibet". Rossabi and Sperling note that this trade in Tibetan horses for Chinese tea existed long before the Ming. Peter C. Perdue says that Wang Anshi (1021–1086), realizing that China could not produce enough militarily capable steeds, had also aimed to obtain horses from Inner Asia in exchange for Chinese tea. The Chinese needed horses not only for cavalry but also as draft animals for the army's supply wagons. The Tibetans required Chinese tea not only as a common beverage but also as a religious ceremonial supplement. The Ming government imposed a monopoly on tea production and attempted to regulate this trade with state-supervised markets, but these collapsed in 1449 due to military failures and internal ecological and commercial pressures on the tea-producing regions.
Document 9: Sino-Tibetan relations during the Ming dynasty: Laird writes that Altan Khan abolished the native Mongol practices of shamanism and blood sacrifice, while the Mongol princes and subjects were coerced by Altan to convert to Gelug Buddhism—or face execution if they persisted in their shamanistic ways. Committed to their religious leader, Mongol princes began requesting the Dalai Lama to bestow titles on them, which demonstrated "the unique fusion of religious and political power" wielded by the Dalai Lama, as Laird writes. Kolmaš states that the spiritual and secular Mongol-Tibetan alliance of the 13th century was renewed by this alliance constructed by Altan Khan and Sönam Gyatso. Van Praag writes that this restored the original Mongol patronage of a Tibetan lama and "to this day, Mongolians are among the most devout followers of the Gelugpa and the Dalai Lama." Angela F. Howard writes that this unique relationship not only provided the Dalai Lama and Panchen Lama with religious and political authority in Tibet, but that Altan Khan gained "enormous power among the entire Mongol population."
Document 10: 2008 Summer Olympics torch relay: Some advocates for Tibet, Darfur, and the spiritual practice Falun Gong, planned to protest the April 9 arrival of the torch in San Francisco. China had already requested the torch route in San Francisco be shortened. On April 7, 2008, two days prior to the actual torch relay, three activists carrying Tibetan flags scaled the suspension cables of the Golden Gate Bridge to unfurl two banners, one saying "One World, One Dream. Free Tibet", and the other, "Free Tibet '08". Among them was San Francisco resident Laurel Sutherlin, who spoke to the local TV station KPIX-CBS5 live from a cellphone, urging the International Olympic Committee to ask China not to allow the torch to go through Tibet. "Sutherlin said he was worried that the torch's planned route through Tibet would lead to more arrests and Chinese officials would use force to stifle dissent." The three activists and five supporters face charges related to trespassing, conspiracy and causing a public nuisance.
Document 11: Sino-Tibetan relations during the Ming dynasty: While the Ming dynasty traded horses with Tibet, it upheld a policy of outlawing border markets in the north, which Laird sees as an effort to punish the Mongols for their raids and to "drive them from the frontiers of China." However, after Altan Khan (1507–1582)—leader of the Tümed Mongols who overthrew the Oirat Mongol confederation's hegemony over the steppes—made peace with the Ming dynasty in 1571, he persuaded the Ming to reopen their border markets in 1573. This provided the Chinese with a new supply of horses that the Mongols had in excess; it was also a relief to the Ming, since they were unable to stop the Mongols from periodic raiding. Laird says that despite the fact that later Mongols believed Altan forced the Ming to view him as an equal, Chinese historians argue that he was simply a loyal Chinese citizen. By 1578, Altan Khan formed a formidable Mongol-Tibetan alliance with the Gelug that the Ming viewed from afar without intervention.
Document 12: 2008 Summer Olympics torch relay: Up to 600 pro-Tibet protesters were expected to attend the relay, along with between 2,000 and 10,000 Chinese supporters. Taking note of the high number of Chinese supporters, Ted Quinlan, head of the Canberra torch relay committee, said: "We didn't expect this reaction from the Chinese community. It is obviously a well-coordinated plan to take the day by weight of numbers. But we have assurances that it will be done peacefully.". Also, Australia's ACT Chief Minister, Jon Stanhope confirmed that the Chinese embassy was closely involve to ensure that "pro-China demonstrators vastly outnumbered Tibetan activists." Australian freestyle swimmer and five-time Olympic gold medalist Ian Thorpe ended the Australian leg of the torch relay April 24, 2008, touching the flame to light a cauldron after a run that was only marginally marked by protests. People demonstrated both for China and for Tibet. At least five people were arrested during the torch relay. Police said "the five were arrested for interfering with the event under special powers enacted in the wake of massive protests against Chinese policy toward Tibet." At one point, groups of Chinese students surrounded and intimidated pro-Tibet protesters. One person had to be pulled aboard a police launch when a group of pro-Chinese students looked like they might force him into the lake.
Document 13: 2008 Summer Olympics torch relay: Following the events in Olympia, there were reports that China requested permission to deploy People's Liberation Army personnel along the relay route to protect the flame in Canberra. Australian authorities stated that such a request, if it were to be made, would be refused. Chinese officials labeled it a rumor. Australian police have been given powers to search relay spectators, following a call by the Chinese Students and Scholars Association for Chinese Australian students to "go defend our sacred torch" against "ethnic degenerate scum and anti-China separatists". Tony Goh, chairman of the Australian Council of Chinese Organisations, has said the ACCO would be taking "thousands" of pro-Beijing demonstrators to Canberra by bus, to support the torch relay. Zhang Rongan, a Chinese Australian student organising pro-Beijing demonstrations, told the press that Chinese diplomats were assisting with the organization of buses, meals and accommodation for pro-Beijing demonstrators, and helping them organise a "peaceful show of strength". Foreign Minister Stephen Smith said Chinese officials were urging supporters to "turn up and put a point of view", but that he had no objection to it as long as they remained peaceful.
Document 14: 2008 Summer Olympics torch relay: In many cities along the North American and European route, the torch relay was protested by advocates of Tibetan independence, animal rights, and legal online gambling, and people protesting against China's human rights record, resulting in confrontations at a few of the relay locations. These protests, which ranged from hundreds of people in San Francisco, to effectively none in Pyongyang, forced the path of the torch relay to be changed or shortened on a number of occasions. The torch was extinguished by Chinese security officials several times during the Paris leg for security reasons, and once in protest in Paris.
Document 15: Sino-Tibetan relations during the Ming dynasty: Kolmaš writes that, as the Mongol presence in Tibet increased, culminating in the conquest of Tibet by a Mongol leader in 1642, the Ming emperors "viewed with apparent unconcern these developments in Tibet." He adds that the Ming court's lack of concern for Tibet was one of the reasons why the Mongols pounced on the chance to reclaim their old vassal of Tibet and "fill once more the political vacuum in that country." On the mass Mongol conversion to Tibetan Buddhism under Altan Khan, Laird writes that "the Chinese watched these developments with interest, though few Chinese ever became devout Tibetan Buddhists."
