From that time, in spite of the remonstrances of the Chinese government, the exportation of opium from India to China continued, increasing from 52,925 piculs (of 1333 lb) in 1850 to 96,839 piculs in 1880.
The western provinces of Sze-ch`uen, Yun-nan and Kwei-chow yielded respectively 200,000, 30,000 and 15,000 piculs (of 1 333 Ib); Manchuria 15,000; Shen-si, Chih-li and Shan-tung io,000 each; and the other provinces from 5000 to 500 piculs each, the whole amount produced in China in 1906 being estimated at 330,000 piculs, of which the province of Sze-ch`uen produced nearly twothirds.
Of this amount China required for home consumption 325,270 piculs, the remainder being chiefly exported to IndoChina, whilst 54,225 piculs of foreign opium were imported into China.
The average annual import of Persian and Turkish opium into China is estimated at 1125 piculs, and if this quantity were to be reduced every year by one-ninth, beginning in 1909, in nine years the import into China would entirely cease, and the Indian, Persian and Turkish opiums no longer be articles of commerce in that country.
About half of the total produce finds its way to the Chinese market, chiefly by sea to Hongkong and the Federated Malay States, although some is carried overland through Bokhara, Khokand and Kashgar; a small quantity is exported by way of Trebizond and Samsun to Constantinople, and about 2000 piculs to Great Britain.
