The Britain signed the treaties with the Qing government (the last dynasty in China until 1912), and the bearer shares of the treaties were brought to Taiwan by the KMT government before 1950. So the issue is: who represents China? The government in Beijing or the government in Taipei? Later, Britain signed the Sino–British Joint Declaration of 1984 with Beijing to decide the (then) future of Hong Kong. If the Sino–British Joint Declaration is revoked, things could be different. Just recently US is asking the Beijing government to repay the debt of Qing dynasty [1], which Beijing said would be the responsibility of Taiwan. Following this logic, receiving Hong Kong from Britain could also be the responsibility of Taiwan.
