Donald Trump announced an ambitious defence project worth $175 (CAD 240) billion. This project, called the Golden Dome, aims to protect the USA from missile attacks, even from those launched from space.

Trump's plans to build a "Golden Dome" U.S. missile defense system undermine "global strategic balance and stability," and should be abandoned, China says.

Donald Trump unveiled concepts for his £400 billion Golden Dome missile defence program at the White House, which he hopes will be "fully operational" before the end of his term in 2029

However, China has expressed serious concerns over the project, with Foreign Ministry spokesperson Mao Ning stating that it carries "strong offensive implications" and heightens the risks of militarisation of outer space and an arms race.

Trump estimated the Golden Dome project to cost $175 billion, with a $25 billion down payment. A recent Congressional Budget Office estimate put the total cost of deploying and operating a constellation of space-based interceptors for 20 years at anywhere from $161 billion to $831 billion.
