Nixon's 1972 visit to China achieved all of the following EXCEPT:
- the USSR withdraws its troops from Afghanistan
- China begins to resume world relations
- China and the USSR are further separated
- the USSR is more willing to make concessions to US demands
Nixon's visit to China in 1972 did not lead to the USSR withdrawing its troops from Afghanistan. This event occurred in 1979 when the Soviet Union invaded Afghanistan, leading to a prolonged conflict that lasted for years. Nixon's visit, however, was significant in improving relations between the US and China, opening up diplomatic channels and reshaping the geopolitical landscape of the time. It did not directly impact the Soviet Union's military involvement in Afghanistan.
