China, Taiwan, and Singapore are three countries where Mandarin Chinese is spoken widely.
China and Singapore would be the only two countries that I know of that have Chinese as an offical language- also people speaking Chinese can be found in most countries.
Because in China, citizens speak Chinese and in the USA citizens speak American. So immigrants have to adapt to their customs not the other way around.
Two independent countries have Chinese as the predominant mother tongue and official language: the People's Republic of China and the Republic of China (also known as Taiwan).
Anywhere in the where there is or has been a Chinese immigrant community, there are likely to be Mandarin Chinese speakers. The largest number of speakers is in the People's Republic of China.
China, Taiwan, Singapore, and Malaysia are countries where Chinese is spoken. Chinese is also spoken by significant populations in countries like Hong Kong, Macau, and various Chinese communities around the world.
About 90% of China's population speaks Chinese.
