"The Chinese side is continuing to closely follow the US action which may influence the security of outer space and may harm other countries," said Foreign Ministry spokesman Liu Jianchao.

Nuclear and other weapons of mass destruction are banned from space under a 1967 international treaty, but Washington's plans have caused concerns about non-nuclear arms in space.
