Sino-US Relations (Group work question)

GROUP QUESTION (#5 ON PAPER ABOUT SINO-US RELATIONS sources A-C)

There is some evidence in Sources A-C to support the concept that the change in relations between the USA and the PRC was less fundamental than is sometimes supposed.
Source A says that "China's attitude toward foreign countries retains elements of aloofness, suspicion and hostility."
Source B says that China and the US were friendly but didn't like each other's foreign policies; the nationalists still think that they are right in choosing their nationalistic views...
Sources C (ii) and (iii) do not offer any specific evidence to support the fundamentality of the change in relations between the USA and the PRC; the supposed quote 'today our two peoples hold in their hand the future of the whole world' has no real power or plan behind it, it's just a nice-sounding statement, and if the change in relations had been that drastic and meaningful, there would be specific planning going on between them.

There is some evidence in sources A-C that the changes in relations between USA and the PRC in 1971 were less fundamental than is sometimes supposed. In source A, it is mentioned that China's foreign policy is still very hostile towards other countries. It is said that they are booth aloof and suspicious. Source B initially seems to support the idea that the change in Sino-US relations was great, but later on it goes on to mention that the relationships between the countries had been suspended for twenty years. Source C mentions that three-corner diplomacy was advantageous to the United States, showing that the US is still sticking to their own ways. There is façade of agreement, but really every country is still looking out for their own interests.
