Sino-American Relations

"No great realignment." What evidence is contained in all of the Sources A-C that the changes in the relations between the USA and the PRG in 1971 were less fundamental than is sometimes supposed?

Source A states that China has had little experience of conducting diplomacy based on the sovereign equality of nations. It also states the China's attitude toward foreign countries retains elements of aloofness, suspicion and hostility. This shows that China was very inexperienced when forming relations with the US showing it was less than fundamental. In Source B, the US would react with force if any reputation of Republic of China is lost in the UN. This shows that's less fundamental because the UN would still not realize that the communist were in control but believe that the nationalists in Taiwan still had some power. Source B also shows that the US and China, have different fundamentally social systems that lead to fundamentally different governments. In source C, secret meetings were held, and the conversations made were not recorded therefore the only information we have for public statements are, "today our two people as hold in their hand the future of the whole world?" It's less fundamental because the foreign policy changes an the Chinese and Americans are not making public to the people.
