How many countries speak Chinese which are they and their capitals?

It's not accurate to say a certain number of countries "speak" Chinese. Chinese is spoken as a native language in one country:

* China: Capital - Beijing

However, Chinese is also spoken as a second language or minority language in many other countries, particularly in Southeast Asia, due to historical and cultural ties. Here are some examples:

* Singapore: Capital - Singapore (Mandarin is one of the official languages)

* Malaysia: Capital - Kuala Lumpur (Mandarin is a major language spoken by the Chinese Malaysian community)

* Taiwan: Capital - Taipei (Mandarin is the official language)

* Hong Kong: Capital - Hong Kong (Cantonese is the dominant language, Mandarin is also widely spoken)

* Macau: Capital - Macau (Cantonese is the dominant language, Mandarin is also widely spoken)

* Thailand: Capital - Bangkok (Chinese is spoken by the Chinese Thai community)

* Indonesia: Capital - Jakarta (Chinese is spoken by the Chinese Indonesian community)

* Vietnam: Capital - Hanoi (Chinese is spoken by the Chinese Vietnamese community)

* Philippines: Capital - Manila (Chinese is spoken by the Chinese Filipino community)

It's important to note that the number of speakers and the prominence of Chinese in these countries varies significantly. For example, Mandarin is an official language in Singapore, but Cantonese is the dominant language in Hong Kong.
