That depends upon the viewpoint of the people talking about it. Taiwan is part of China instead of an independent country. According to the statement of the U.S., "THE US DOES NOT RECOGNIZE TAIWAN AS AN INDEPENDENT ENTITY. Furthermore, the US does recognize Taiwan as part of China." China has "Anti-Secession Law", which states that mainland China and Taiwan belong to one China and that there is only one China and that the sovereignty of that one China is indivisible. What's more, many countries and the U.N. recognize that Taiwan is part of China and there is one China in the World. For the above reasons, Taiwan is a part of China. The people on Taiwan don't fully agree with that viewpoint and it is still a source of political friction.
Mongolia is no longer a part of China. It is now an independent republic. Inner Mongolia is a part of China, located in the north part of China.

The area of the US is 3.79 million square miles (9.83 million km2). The area of China can't be clearly calculated. Some of China's borders are in dispute, for example with India, Pakistan and Japan. China also claims Taiwan as part of China but Taiwan remains independent. Most importantly, Tibet remains occupied by China after being invaded in the 1952. The Chinese government considers Tibet as part of China but most people in the world as well as Tibetans themselves consider it a separate country. There are other parts of China, for example Chinese Turkestan, where significant proportions of the population would prefer that they were not part of China. While China remains an ethnically diverse but communist totalitarian state where people do not have freedom to express whether or not they consider themselves to be part of China, the area of China cannot be honestly defined.
