YTTSUF 489 YVON Annam, Siam, and Burma; on the W. by Burma; area, 107,969 square miles; pop. about 12,000,000. It is extremely rich in minerals, especially iron and copper, containing also many varieties of precious stones. At least a third of the cultivated land is said to be under the poppy. The inhabitants are for the most part Chinese; but there is a large number of non-Chinese Mohammedans (called by the Burmese Panthays). The chief imports into Yunnan are raw cotton, cotton yarn, and piece goods; opium and tin are the chief ex- ports. In 1869 the Mohammedans rose in rebellion against the Chinese Govern- ment, and succeeded in establishing an independent government, but it lasted only three or four years. By the con- vention of Chefoo in 1876 the establish- ment of commercial relations between British subjects and Yunnan was con- ceded by the Chinese Government. In 1897 an agreement was made be- tween Great Britain and China, supple- menting the Frontier Convention of March, 1894, which laid down a bound- ary between Burma with its dependen- cies and Yunnan and made arrangements for trade, extradition, etc. The ques- tion of access to Yunnan and Szechuen is one of great importance to the com- mercial nations of Europe. The shortest route to Yunnan is through French ter- ritory by the Red river. There are com- peting routes through Burma. A part of .Yunnan is most easilv reached from Bhamo. The Indian railway system is being extended to Kunlong Ferry, on the Sal ween, from which a route to Talifu, and possibly on to Szechuen, may be found practicable. Another route for a railway has been suggested through Chiengmai and northern Siam. More important routes at present are by river up to the Canton or West river, or by the Yang-tze-kiang. By the agreement of Jan. 15, 1896, Great Britain and France agreed to share equally all privi- leges or advantages that might be con- ceded by China in the provinces of Yun- nan and Szechuen. Yunnan, the capital, is in the S. E., and is a busy and prosperous town, with large copper factories, and manufac- tures of silks and carpets. Pop. 200,000.
