Mandarin Chinese includes the basis of Standard Japanese.
 The Chinese government's current goal is to have 85% of China speak Standard Mandarin by 2025 and for virtually the entire country to speak the language by 2035
 Many varieties of Mandarin, such as those of the Southwest (including Sichuanese) and the Lower Yangtze, are not mutually intelligible  with the standard language (or are only partially intelligible)
