China has constructed a mock-up of a key area in Taiwan's capital city, including the presidential office and surrounding government buildings. This mock-up is located in the Alxa League area of Inner Mongolia. Satellite images show that the mock-up is relatively realistic, with roads and buildings closely resembling the actual area in Taipei.

The construction of this mock-up is not the first instance of China building such structures. In 2014 and 2015, China built a mock-up of Taiwan's presidential office at Zhurihe, also in Inner Mongolia. Chinese troops were observed practicing an assault on this mock-up.

China has also built mock-ups of US aircraft carriers and other warships at training sites. These mock-ups are likely used to test and improve China's missiles. Experts have expressed concern about the increasing stockpiles and capabilities of China's Rocket Force and its potential role in a conflict with the United States.

The construction of these mock-ups signals China's intentions and focus. China has been engaging in aggressive and coercive behavior towards Taiwan, including economic, diplomatic, and military tactics. China has also been pursuing a significant military build-up and modernization effort.
