What two strategies were used before Nixon went to china how did this help with the two countries relations

The two strategies used before Nixon went to China were the "Ping-Pong Diplomacy" and the "Back-Channel Diplomacy". The "Ping-Pong Diplomacy" was a strategy of using sports as a way to improve relations between the two countries. The "Back-Channel Diplomacy" was a strategy of using secret negotiations to improve relations between the two countries. Both strategies helped to create a more open dialogue between the two countries and allowed for the eventual visit of President Nixon to China.
