China: The United States and China have set up an emergency direct link between the space and military agencies of both the nations to negate the risk of accidental satellite warfare. This ‘hotline’ will serve as a diplomatic safety valve in times of conflict. A similar direct line of communication already exists between the US and Russia as a legacy of the Cold War. The move comes in the light of China developing a full spectrum of anti-satellite capabilities. The Asian powerhouse even blew up an aging Chinese weather satellite in 2007 while testing its anti-satellite weapon. Destroying satellites at times of war can provide a big advantage by disabling coordination abilities and intelligence efforts of rival nations.
