All three Paper 3 alternatives have introductory context, historiography and original interpretation exercises; Italy, Stalin’s Russia, Hitler’s Germany and Britain have introductory depth pathways across their four enquiries. The USA in the late 1940s/1950s and the 1960s/1970s have introductory American depth pathways; the 1980s/early-1990s theme now introduces all four enquiries with original teaching and two longer essay workshops. All four American themes now have introductory teaching and longer essay workshops, including US foreign policy, 1944–1992. The US–Soviet theme introduces all four enquiries through thirty core lessons and two longer essay workshops. Forty-one lessons introduce all four East and Southeast Asia enquiries: eight on post-war change, nine on Korea, twelve on Vietnam and twelve on Sino-American relations. Eight lessons introduce the African independence enquiry through Ghana, Nigeria, Senegal, Kenya and comparative reasoning. Nine further lessons introduce government, economic and social challenges after independence. Thirteen further lessons introduce Cold War involvement, Chinese support, non-alignment and Pan-Africanism. Twelve further lessons introduce UN involvement in Congo and Somalia, with 1993–1995 explicitly labelled as later context beyond the theme’s 1992 endpoint. Ten lessons introduce the creation-of-Israel enquiry. Twenty further lessons introduce wars and peace efforts in 1948–1979. Seventeen further lessons introduce superpower motives, oil, American and Soviet policies and their consequences through 1991.

Compare after trying
Normalisation was a major change because it replaced an intermediate relationship with formal diplomatic mechanisms while reorganising Washington’s Taiwan relationship. Liaison offices opened in 1973 had enabled useful contact, but Taiwan and domestic political objections still obstructed full relations. Carter’s settlement therefore built on Nixon’s opening without being an automatic consequence already completed in 1972.
The documents show precisely what changed. The December 1978 announcement preceded relations from January 1979 and the specified March embassy stage. Recognition of the PRC government, acknowledgement of the Chinese Taiwan position and continuing unofficial ties were different provisions. The defence treaty also had a separate notice and one-year termination process. Overall, normalisation expanded the institutions through which shared interests and disputes could be managed; it did not eliminate the disputes or require every practical Taiwan link to end at once. A stronger judgement compares the strategic and political reasons for the bargain with the differentiated arrangements that made it possible, rather than using one label to erase the stages and qualifications recorded in the agreement.
Why this response fits
- Connect evidence to a specific causal mechanism and outcome.
- Compare explanations and keep contemporary claims, later interpretation and verified events distinct.
- This original analytical model is not a calibrated examination script or Cambridge grade.
Explain an intermediate relationship
The United States and PRC opened liaison offices in their capitals in 1973. These provided practical channels for contact without the full diplomatic relationship later established in 1979. An office could perform important work while its formal status remained different from an embassy. This intermediate arrangement shows both the value attached to improved communication and the difficulty of resolving political obstacles after the Shanghai opening.
Taiwan remained central. Washington still had a formal relationship with the ROC and a defence treaty, while Beijing opposed arrangements implying two Chinese governments with equal international legitimacy. American domestic politics also constrained change: leaders faced criticism that altering the relationship would abandon an ally or reward a communist opponent. The opportunity created in 1972 therefore required further bargaining and choices rather than unfolding on an automatic timetable.
Read the announcement and its attached statements
A 15 December 1978 backchannel message to Ambassador Unger set out the forthcoming announcement and the planned change in relations with Taiwan. The attached public joint communiqué provided for US–PRC diplomatic relations from 1 January 1979 and exchange of ambassadors and establishment of embassies on 1 March. Announcement, effective relations and the embassy stage were three distinct points, not three different agreements to be collapsed into one date.
The United States recognised the PRC government as the sole legal government of China. The text separately acknowledged the Chinese position concerning one China and Taiwan and retained cultural, commercial and other unofficial relations with the people of Taiwan. Those verbs and objects matter. Recognition of a government should not be rewritten as identical independent wording on every territorial question or as a promise that all practical Taiwan relationships would disappear.
Separate a commitment from its implementation and reception
The message also said formal notice would be given on 1 January to terminate the US–ROC defence treaty after one year, using Article X. Ending diplomatic relations and the treaty’s termination timetable were therefore different matters. The January effective date did not itself mean that every troop, agreement and commercial contact vanished at the same instant. Read each category rather than assuming that one status change mechanically ended all others.
Carter’s decision built on Nixon’s opening and the intermediate relationship but still represented a new negotiated settlement. Strategic interest, economic possibilities and domestic arguments affected its timing, while the parties retained different preferences over Taiwan and arms. Assess normalisation as a major institutional change that created regular mechanisms for diplomacy, not as proof of universal approval or the end of all disputes. The next lesson examines the domestic legislation through which Washington organised continuing unofficial ties.

Test this topic →From guided practice to a new situation
Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
Guided: Explain why liaison offices do not make the 1979 decision redundant.
Give me a hint
Compare useful contact with full diplomatic status.
Compare my reasoning
- Identify the 1973 intermediate channel.
- Identify the unresolved political issue.
- Explain the later institutional change.
Liaison offices enabled practical communication after the opening without settling the full diplomatic relationship or Taiwan arrangements. The later bargain changed recognition and established formal relations and embassy mechanisms. It was therefore a further institutional decision built on an intermediate channel, not a duplicate event with no new political consequences.
Look for these in your work
- Distinguishes practical function and status
- Explains continuity with change
Independent: Put the three announcement and implementation stages in order.
Give me a hint
Use the joint communiqué and the message date.
Compare my reasoning
- Locate December announcement.
- Locate January effective relations.
- Locate March embassy provision.
The announcement came in December 1978, formal relations were to begin on 1 January 1979, and the joint communiqué specified exchange of ambassadors and establishment of embassies on 1 March. These stages concerned different functions. A precise account does not date formal relations to the earlier Shanghai visit or move the embassy provision into December.
Look for these in your work
- Preserves chronological order
- Identifies what each date means
Application: Correct an argument that the defence treaty ended with the December announcement.
Give me a hint
Read the separate notice and Article X.
Compare my reasoning
- Identify the planned notice date.
- Identify the one-year term.
- Separate diplomatic and treaty stages.
The message planned formal notice on 1 January 1979 leading to termination after one year under Article X. That timetable was separate from the December announcement and the January end of formal US–ROC diplomatic relations. Treating all of them as an immediate December termination removes a distinction expressly retained in the documents.
Look for these in your work
- Uses the notice provision
- Separates kinds of legal and diplomatic change
Common mistakes
- Calling liaison offices full embassies in 1973
- Merging December announcement, January relations and March embassies
- Making treaty termination identical to the announcement date
