The founder of the Sung dynasty, Chao K'uang-yin, came of a Chinese military family living to the south of Peking. He advanced from general to emperor, and so differed in no way from the emperors who had preceded him. But his dynasty did not disappear as quickly as the others; for this there were several reasons. To begin with, there was the simple fact that he remained alive longer than the other founders of dynasties, and so was able to place his rule on a firmer foundation. But in addition to this he followed a new course, which in certain ways smoothed matters for him and for his successors, in foreign policy.

This Sung dynasty, as Chao K'uang-yin named it, no longer turned against the northern peoples, particularly the Kitan, but against the south. This was not exactly an heroic policy: the north of China remained in the hands of the Kitan. There were frequent clashes, but no real effort was made to destroy the Kitan, whose dynasty was now called "Liao". The second emperor of the Sung was actually heavily defeated several times by the Kitan. But they, for their part, made no attempt to conquer the whole of China, especially since the task would have become more and more burdensome the farther south the Sung expanded. And very soon there were other reasons why the Kitan should refrain from turning their whole strength against the Chinese.

As we said, the Sung turned at once against the states in the south. Some of the many small southern states had made substantial economic and cultural advance, but militarily they were not strong. Chao K'uang-yin (named as emperor T'ai Tsu) attacked them in succession. Most of them fell very quickly and without any heavy fighting, especially since the Sung dealt mildly with the defeated rulers and their following. The gentry and the merchants in these small states could not but realize the advantages of a widened and well-ordered economic field, and they were therefore entirely in favour of the annexation of their country so soon as it proved to be tolerable. And the Sung empire could only endure and gain strength if it had control of the regions along the Yangtze and around Canton, with their great economic resources. The process of absorbing the small states in the south continued until 980. Before it was ended, the Sung tried to extend their influence in the south beyond the Chinese border, and secured a sort of protectorate over parts of Annam (973). This sphere of influence was politically insignificant and not directly of any economic importance; but it fulfilled for the Sung the same functions which colonial territories fulfilled for Europeans, serving as a field of operation for the commercial class, who imported raw materials from it--mainly, it is true, luxury articles such as special sorts of wood, perfumes, ivory, and so on--and exported Chinese manufactures. As the power of the empire grew, this zone of influence extended as far as Indonesia: the process had begun in the T'ang period. The trade with the south had not the deleterious effects of the trade with Central Asia. There was no sale of refined metals, and none of fabrics, as the natives produced their own textiles which sufficed for their needs. And the export of porcelain brought no economic injury to China, but the reverse.

This Sung policy was entirely in the interest of the gentry and of the trading community which was now closely connected with them. Undoubtedly it strengthened China. The policy of nonintervention in the north was endurable even when peace with the Kitan had to be bought by the payment of an annual tribute. From 1004 onwards, 100,000 ounces of silver and 200,000 bales of silk were paid annually to the Kitan, amounting in value to about 270,000 strings of cash, each of 1,000 coins. The state budget amounted to some 20,000,000 strings of cash. In 1038 the payments amounted to 500,000 strings, but the budget was by then much larger. One is liable to get a false impression when reading of these big payments if one does not take into account what percentage they formed of the total revenues of the state. The tribute to the Kitan amounted to less than 2 per cent of the revenue, while the expenditure on the army accounted for 25 per cent of the budget. It cost much less to pay tribute than to maintain large armies and go to war. Financial considerations played a great part during the Sung epoch. The taxation revenue of the empire rose rapidly after the pacification of the south; soon after the beginning of the dynasty the state budget was double that of the T'ang. If the state expenditure in the eleventh century had not continually grown through the increase in military expenditure--in spite of everything!--there would have come a period of great prosperity in the empire.
