President Trump's missile defense project, called the "Golden Dome for America," aims to protect the U.S. from foreign threats. But it has a steep price and has been criticized by China as threatening to increase the risks of militarizing space and a global arms race.

U.S. President Donald Trump said on Tuesday he had selected a design for the project and named a Space Force general to head the ambitious program aimed at blocking threats from China and Russia.

China is concerned by President Donald Trump's proposal for a new U.S. missile defense system, called the Golden Dome, which is designed to protect against adversarial attacks on America.
