In what way did Richard Nixon's 1972 trip to China impact the US's diplomacy with the Soviet Union?

On February 21, 1972, President Richard M. Nixon arrived in China for an official trip. He was the first U. S. president to visit the People's Republic of China since it was established in 1949. This was an important event because the U. S. was seeking to improve relations with a Communist country during the Cold War.
