“At their summit, Nixon and Soviet leader Leonid Brezhnev signed the Strategic Arms Limitation Treaty (SALT I), the first arms control measure that the United States agreed to since the start of the Cold War.”
First of all, the visit was very significant, because no other president (except for Roosevelt) had ever went to the communist USSR before. Since the United States had always feared and fought communism and communistic countries, the “goodwill” visit to one of those countries meant a change in politics. As Freeman said it didn’t mean that the White House became more tolerant to communism, but it did mean that method of fighting it had changed. Instead of confronting each other they decided to be “friends”. If during the Cold War the two countries competed with each other in many aspects like military, science, innovations, etc. So after the visit they actually agreed on not only Arms Limitation Treaty, but on other joint projects in science and trade. For instance, during that visit was created an agreement to import Coca-Cola and created a project to build the first Coca-Cola factory in the USSR, which was completed in 1974 in Novorossiysk. This was a big deal in the USSR.
