February 2022 marks the 50th anniversary of former US president Richard Nixon's historic trip to China in 1972.Along with his national security adviser Dr.Henry Kissinger,Nixon met with Chinese Chairman Mao Zedong and premier Zhou Enlai.Concluding with the joint statement known as the Shanghai Communique,the visit paved the way for the establishment of formal relations between the two countries in 1979.Referred to by Nixon as“the week that changed the world”and described by Zhou as an event that“would shake the world,”the visit triggered a geopolitical earthquake,tipping the balance of the rivalry between the US and the Soviet Union.But as the China-US relationship has taken a downturn in recent years,the historic significance of Nixon's trip has been increasingly challenged and opened to reinterpretation in the US,which poses risks to Sino-US relations。
