"On January 12, the lower house of the Tajik parliament voted to ratify the 2002 border demarcation agreement, handing over 1,122 square kilometers (433 square miles) of mountainous land in the remote Pamir Mountains (www.asiaplus.tj, January 12). The ceded land represents about 0.8 percent of the country’s total area of 143,100 square kilometers (55,250 square miles).{...}At the time of independence, Tajikistan inherited three disputed border segments, constituting about 28,500 square kilometers (11,000 square miles), which China and the Soviet Union had been unable to resolve. In 1999, Tajikistan and China signed a border demarcation agreement, defining the border in two of the three segments. Under the 1999 deal, Dushanbe ceded about 200 square kilometers (77 square miles) of land to Beijing (http://www.ca-oasis.info/oasis/?jrn=109&id=817)."

Eurasianet. 2020年8月7日閲覧。 “Days later, an article appeared in Chinese news outlets claiming that Tajikistan’s Pamir mountains historically belonged to China and should be returned. Though the article was penned by a nationalist historian and does not appear to be a veiled hint from the Party, the message hit Dushanbe in a sensitive spot. Tajik officials are perennially concerned about the Pamirs, a region where they have tenuous authority over the local population.”
