Question: By what name is the Brahmaputra known in Bangladesh, and the region that the Ming once traded horses with?

full_context: Document 1: Tibet: Tibet has some of the world's tallest mountains, with several of them making the top ten list. Mount Everest, located on the border with Nepal, is, at 8,848 metres (29,029 ft), the highest mountain on earth. Several major rivers have their source in the Tibetan Plateau (mostly in present-day Qinghai Province). These include the Yangtze, Yellow River, Indus River, Mekong, Ganges, Salween and the Yarlung Tsangpo River (Brahmaputra River). The Yarlung Tsangpo Grand Canyon, along the Yarlung Tsangpo River, is among the deepest and longest canyons in the world.
Document 2: Brahmaputra River: The Brahmaputra (/ ˌbrɑːməˈpuːtrə / is one of the major rivers of Asia, a trans - boundary river which flows through China, India and Bangladesh. As such, it is known by various names in the region: Assamese: ব্ৰহ্মপুত্ৰ নদ ('নদ' nôd, masculine form of 'নদী' nôdi ``river '') Brôhmôputrô (bɹɔɦmɔputɹɔ); Sanskrit: ब्रह्मपुत्र, IAST: Brahmaputra; Tibetan: ཡར ་ ཀླུངས ་ གཙང ་ པོ ་, Wylie: yar klung gtsang po Yarlung Tsangpo; simplified Chinese: 布拉马普特拉河; traditional Chinese: 布拉馬普特拉河; pinyin: Bùlāmǎpǔtèlā Hé. It is also called Tsangpo - Brahmaputra (when referring to the whole river including the stretch within Tibet). The Manas River, which runs through Bhutan, joins it at Jogighopa, in India. It is the ninth largest river in the world by discharge, and the 15th longest.
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: Tibet: The Indus and Brahmaputra rivers originate from a lake (Tib: Tso Mapham) in Western Tibet, near Mount Kailash. The mountain is a holy pilgrimage site for both Hindus and Tibetans. The Hindus consider the mountain to be the abode of Lord Shiva. The Tibetan name for Mt. Kailash is Khang Rinpoche. Tibet has numerous high-altitude lakes referred to in Tibetan as tso or co. These include Qinghai Lake, Lake Manasarovar, Namtso, Pangong Tso, Yamdrok Lake, Siling Co, Lhamo La-tso, Lumajangdong Co, Lake Puma Yumco, Lake Paiku, Lake Rakshastal, Dagze Co and Dong Co. The Qinghai Lake (Koko Nor) is the largest lake in the People's Republic of China.
Document 5: Indus River: The Indus River (locally called Sindhū) is one of the longest rivers in Asia. Originating in the Tibetan Plateau in the vicinity of Lake Manasarovar, the river runs a course through the Ladakh region of Jammu and Kashmir, towards Gilgit - Baltistan and the Hindukush ranges, and then flows in a southerly direction along the entire length of Pakistan to merge into the Arabian Sea near the port city of Karachi in Sindh. It is the longest river and national river of Pakistan.
Document 6: 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 7: 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 8: Mekong: The Mekong is a trans - boundary river in Southeast Asia. It is the world's twelfth longest river and the seventh longest in Asia. Its estimated length is 4,350 km (2,703 mi), and it drains an area of 795,000 km (307,000 sq mi), discharging 475 km (114 cu mi) of water annually.
Document 9: Kameng River: The Kameng River (previously named Bhareli River (ভৰলী নদী), now called Kameng in Arunachal Pradesh and Jia Bhoreli in Assam) in the eastern Himalayan mountains, originates in Tawang district from the glacial lake below snow-capped Gori Chen mountain , elevation , on the India-Tibet border in South Tibet and flows through Bhalukpong circle of West Kameng District, Arunachal Pradesh and Sonitpur District of Assam, India. It is one of the major tributaries of the Brahmaputra River, joining it at Tezpur, just east of the Kolia Bhomora Setu bridge.
Document 10: Indo-Gangetic Plain: The Indus–Ganga plains, also known as the "Great Plains", are large floodplains of the Indus, Ganga and the Brahmaputra river systems. They run parallel to the Himalaya mountains, from Jammu and Kashmir and Khyber Pakhtunkhwa in the west to Assam in the east and draining most of Northern and Eastern India. The plains encompass an area of 700,000 km2 (270,000 sq mi) and vary in width through their length by several hundred kilometres. The major rivers of this system are the Ganga and the Indus along with their tributaries; Beas, Yamuna, Gomti, Ravi, Chambal, Sutlej and Chenab.
Document 11: 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 12: 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 13: 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."
Document 14: Ganges Delta: The Ganges - Brahmaputra Delta (also known as the Brahmaputra Delta, the Sunderbans Delta or the Bengal Delta) is a river delta in the Bengal region of the South Asia, consisting of Bangladesh and the Indian state of West Bengal. It is the world's largest delta and empties into the Bay of Bengal. It is also one of the most fertile regions in the world, thus earning the nickname The Green Delta. The delta stretches from the Hooghly River on the west to the Meghna River on the east. It is approximately 354 km (220 mi) across at the Bay of Bengal. Kolkata in India and Mongla in Bangladesh are the principal seaports of the delta.
Document 15: 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."
