Abstract:In early 19th century, shortly after the establishment of the British colony of New South Wales, Britain focused on internal affairs of the colony , paying little attention to the surrounding conditions. Consequently, many “beachcombers” became rampant instead endangering the order between the land and sea in the South Pacific. Since the mid-19th century, due to the expansion of its own power and the influence of the international situation, Britain began to send resident, consuls and other diplomatic personnel to the South Pacific region as local agents and policy promoters. In terms of identity, many British diplomats had missionary background. Under the influence of humanism they paid more attention to the land-and-sea order in the South Pacific, and strongly condemned and resisted the soaring labor trade, thus demanding the expansion of their own authority. From the appointment of William Pritchard as Consul to Fiji in 1857, the British political debate on consular jurisdiction began to deepen. Pritchard himself wanted to extend consular powers by contracting with local chiefs, and thus continue to play a role in restricting the human trade , but this was not approved by the British government. On the one hand , although the British government was determined to crack down on the illegal human trade , some existing laws had defined the functions and powers of consuls , which was not an easy legal dilemma to overcome. On the other hand, Britain did not want to expand the empire too much and take on additional political and economic responsibilities , so its overall strategy in the South Pacific was mainly conservative. The establishment of an indigenous Fijian government in 1871 caused the loss of the political environment for further extension of consular jurisdiction , which could have led to disputes with other countries. In the end , Britain?s consular jurisdiction in Fiji only experienced a short-time existence and practice. Although some humanitarian factors had positive effects , it was still a part of Britain' s overseas policy in essence , and a tool for modern imperialism and colonialism to violate the sovereignty of other countries.
