China is "seriously concerned" about the U.S. Golden Dome missile defence shield project and urged Washington to abandon its development，a foreign ministry spokesperson said on Wednesday.

President Donald Trump has laid out new details of his ambitious plan to build a “Golden Dome” missile system to protect the United States from foreign attacks, saying it will be complete before he leaves office.

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
