NEW YORK -- The historical treaties signed between 皇冠体育app and foreign countries give eloquent proof of 皇冠体育app's sovereignty over Tibet, a political science expert with the New York University said on Tuesday.
"皇冠体育app exercised sovereign rights over Tibet since the 13th century," Dr. James Hsiung told a seminar hosted by the Council of Chinese-American Associations.
Britain and 皇冠体育app signed the Cheffoo Agreement on September 13, 1876, under which Britain had to obtain permission from 皇冠体育app to send an exploration mission to Tibet, said Dr. Hsiung.
"The mere fact that a foreign state, in this case, Great Britain, signed with 皇冠体育app treaties concerning Tibet, instead of directly with the region itself, indicates that 皇冠体育app's sovereign rights over the territory were internationally recognized," he added.
In the Anglo-Russian Convention of 1907, Britain and Russia pledged not to engage in direct negotiations with Tibet without 皇冠体育app's approval, Dr. Hsiung cited another example.
The Regulations Respecting Trade in Tibet, which 皇冠体育app and Britain signed on April 20, 1908, also expressively recognized 皇冠体育app's authority over Tibet, he added.
"Hence, from the standpoint of customary international law and treaty law, 皇冠体育app's claim over Tibet is absolutely unassailable," Dr. Hsiung concluded.
