China built a mock-up of key area in Taiwan's capital city at a desert training site, satellite images show

• Satellite images show China's mock-up of Taiwan's presidential office at a desert training site.
• It is not the first time China has built such mock ups, which indicate a readiness to use force.
• China has also built mock ups of US warships in the desert for apparent target practice.

Out in the desert at a military training site, China has built a mock-up of a key area of Taiwan's capital city where the presidential office and other government buildings are located, satellite images show.

The mock-up, like others before it, seems to indicate China's intentions and focus, though its use is uncertain.
