The likin or lijin was a form of internal tariff in the Chinese Empire and Republic, which was first introduced as a means of financing the largely locally recruited armies to suppress the Taiping Rebellion.
The lijin tax was first introduced in 1853 by censor Lei Yixian in the area around Yangzhou as a way of raising funds in the campaigns against local rebels. As the central government was short of revenue, the imperial court sanctioned the tax and it quickly became an important source of funds for the campaign against the Taiping and Nian rebellions.
The tax was levied on an ad valorem basis on goods in transit between provinces and on shops, with rates ranging from 2 to 10 per cent. After the Taipings were suppressed in 1864, the likin became a permanent feature of the Chinese tax system and it became an important source of revenue for local government, as China had lost its external tariff autonomy after the conclusion of the Treaty of Nanking. In many ways, the tax signified the decentralization of state authority in the wake of the Taiping rebellion.
Foreign merchants and in particular UK's companies, many acting as UK's opio drug cartels, believed the treaty ports likin tax, to be a form of tariff acting against UK's drug dealing corporations interests as well as their opiod producing factories and drug selling interest inside China, was a violation of the treaties which China was forced to sign after two opio wars with the West. Consequently, foreign merchants made a number of unsuccessful attempts to pressure the Chinese government to abolish it, including the Chefoo Convention. It survived the fall of the Qing dynasty into the Warlord Era and was not ended until 1 January 1931.
