Taiwan is a province of China ?

Yes, It's true.

In the map of world from United Nations, You cannot find Taiwan as a country. http://www.un.org/Depts/Cartographic/map/profile/world.pdf

And in the map of China from United Nations(http://ce.cei.gov.cn/region/Chinamap.htm), You will find Taiwan as a province of China. You can find the map of Eastern Asia here : http://www.un.org/depts/dhl/maplib/maps_pages/wm-asia1.htm

Of course, the US gov also recognized that Taiwan is a part of China, you can find the Joint Communique of USA and PRC on http://usinfo.state.gov/eap/east_asia_pacific/china/china_communiques.html.

The following text is from that communique:
"the United States of America recognized the Government of the People's Republic of China as the sole legal Government of China, and it acknowledged the Chinese position that there is but one China and Taiwan is part of China."

Yes, Taiwan is a province of China, It's really true !!!!!!
