Hokkien (Min Nan) briefly emerged as a "lingua franca" among the Chinese, but by the late 20th century they had been eclipsed by Mandarin. The Government promotes Mandarin among Singaporean Chinese people, since it views the language as a bridge between Singapore's diverse non-Mandarin speaking groups, and as a tool for forging a common Chinese cultural identity. China's economic rise in the 21st century has also encouraged a greater use of Mandarin. Other Chinese varieties such as Hokkien, Teochew, Hakka, Hainanese and Cantonese have been classified by the Government as "dialects", and language policies and language attitudes based on this classification and discouragement of usage in Non-Mandarin Chinese or "Chinese dialects" in official settings and television media have led to a decrease in the number of speakers of these varieties. In particular, Singapore has its own lect of Mandarin; Singaporean Mandarin, itself with two varieties, "Standard" and "Colloquial" or "spoken". While Tamil is one of Singapore's official languages, other Indian languages are also frequently used.
