The 1858 Sino-British Treaty of Tientsin, which ended the Second Opium War, expanded the rights of western visitors. They were permitted to enter the Chinese interior after passporting. However, extraterritorial rights were not extended outside the treaty ports. Similar rights were granted to the interested western powers due to the "most-favoured-nation" clause: all privileges the Qing empire granted to one powerwere automatically granted to the others. In 1868, when the Tientsin treaties were renegotiated, British merchants clamoured to lift the travel restrictions on the Chinese interior. The Qing position was adamantly opposed, unless extraterritoriality was also abolished. No compromise was reached; and the Qing government was successful in preventing foreigners from visiting the Chinese interior with extraterritorial privileges.
