MŌNG NAI (called by the Burmese and on most old maps Monē), one of the largest and most important of the states in the eastern subdivision of the southern Shan States of Burma. The state of Kéng Tawng (Burmese Kyaing Taung) is a dependency of Mōng Nai. It lies approximately between 20° 10′ and 21° N. and between 97° 30′ and 98° 45′ E., and occupies an area of 2717 sq. m.; pop. (1901), 44,252, of whom more than five-sixths are Shans. The Salween river bounds it on the east. The main state and the sub-state of Kēng Tawng consist of two plains with a ridge between them. There is much flat rice bottom, but a considerable portion consists of gently undulating plain-land. In the central plain rice is the only crop. Outside this considerable quantities of sugar are produced. Tobacco of a quality highly esteemed by the Shans is grown in the Nawng Wawp circle at an altitude of 3100 ft. above sea-level; gram, thanatpet (a leaf used for cigar-wrappers), and garden crops are the chief produce otherwise. In the outlying tracts quantities of coarse native paper are manufactured from the bark of a species of mulberry, and much is exported to other parts of the Shan States.
