1. How did the conditions of trade at Canton offact)

Anglo-Chinese relations up to 18197

Early Anglo-Chinese contact was first started? on a commercial basis. Various attempts of the British East India Company, which enjoyed a monopoly of British överseas trade with the East, in the 17th century to open tradd with China gradually developed into a regular Anglo-Chinego trade at Canton after 1699. Although the French, the Spanish and the Dutch were also trading there, the Company was able to get into its Hands most of China's trade within a short tice, and they established a permanent factory, trading-port, in Ganton in 17155,

Foreign trade at Canton in fact had already had a very long history, yet with the development of this new type of trade with the West and the now. policies of the Ching Government, it gradually became institutionalized into what we may call the Centon

system.

This Canton system consisted of three main | institutions. At the top (after 1685) stood the superintendent of custome for the Kwongtung province: in charge of foreign trade. This was a high officer deputed directly from Peking for the collection and remittance of custom duties, delow this official, whom the foreigners called the "Hoppo", stood the Cohong as the licensed guild of Chinese merchants which consisted of roughly half-a-dozen to a dozen firs which were made responsible for all Western trad and given a monopoly over it. These hỏng merchants also bore responsibility for all forsign ships and traders assecurity merobants": On the side of the foreigners, there were the factories situated on the southern suburb of the Canton city, where the oversea merchants lived and kept their goods and did their business. British merohabts and seamen were under the centrol of the Canton committes of the English” East India Company.

The activities of the foreign meropants wera restinoted by numerous regulations (not to bring in- (foreign miver, not to enter the olty gaten, not to stay in Canten after the trading season, oto.) and they all remained subject to the prodadures Chinese · criminal law. From all thane, we can see that the lisence of the Canton system of trade was monopoly and restriction coupled with rasponsibility.

Although the forsiga merchants and sailors accepted the system quite readily before 1830, they were not satisfied with it. In the first place, they wanted to expand their commerciel opportunities bý the opening of other ports (foreign trade was confined) to Canton after 1757) and by the abolition of the Cohong monopoly, Secondây, they resulted very much the abuses arising out from the monopoly of trade,

“perohants and their hangers-in am well as the attmpt

of the Chinese in keeping them ignorent of sotum. market conditionk. Lastly, they wanted to do away the regulations restricting their activities and to improve their barganing position in legal matters.)

Since the middle of the 18th century, theri had? been constant desande for a change, and importent attempts, were actually made by the East India Company, the Kaneartasy embassey of 1793 and the Amherst mission. of 1816 being the most notable examples. The purpun y of the British was to opan direos contact and negotiation with the Chinese government, and they hoped to establish permanent diplomatie relatione-with Gins. on an equal basis. But the Chinese Government Loud

themselves unable to accept both the commercial sid diplomatic demands of the British. To them, diplomatic relations could only be establimbed on the basis of the traditional tributary systen, which denied the equality of all other nations. As corollary, the Canton system, being an extension if the tributary system, also be upheld.

Therefore, the attempte of the British wors! bound to fail, However, Anglo-Chinese relations at Canton zemained relatively easy at this early stage. (before 1830), because they were handled by a trading company, not a sovereign government. In view of the profitable trade being carried out, the Company wa willing to accept the system without ranging touchy questions such as diplomatic equality, On the other hand, we must understand that with the expansion of trade and growing contacts, the various friations and conflicts between both sides were siso bound to increase with the passage of time. They were problems that had been postponed, but not settled.

The situation changed after 1830. The monopoly of the Company came to an end in 1833, which was followed by a rush of private merchants into Canton, These elemente rapidly dominated the Canton tradı and were ready to exploit every commercial opportunity.. Many of them formed into a new group of aggressiya merchants who would prefer a strong policy against China and influence the home government to underiake such a policy. Secondly, the rapid increase in the smuggle of opium into China alarmed the Chinese officials and ahowed the growing inadequacies of the] sohong monopoly, Free trade doctrines and the Industrialial Revolution in Aritain also called for the expansion of trading opportunities and markets, In the midst of these changes, Anglo-Chinese relatio also underwent a basic change, they were no longər. handled by a trading firm. After 1833, the Briti Chief Superintendent of Trade in China, an official appointed by the British government, began to w represent the British merchants, and the ineritable contanta between the officials of both countries. ineritably brought to the surface all touchy questions,

Lord Faries, the first British Chief Super- intendent of Trade in China, came to Canton in 1834 and had open conflicts with the Chinese officials oven the problem of diplomatic equality. From this time. Conward, tension gradually increased. On the one hand,

there was the British who were determined to forme. open China's doors both diplomatically and commerciall❤ while "on the other there was the Chinese government which was equally determined in suppressing "the

illegal opium trade. As a result, the situation became more and more explosive, and finally led to the

outbreak of the first Anglo-Chinese War in 1839.
