What was the state of China at the Japanese surrender in 1945, and what made renewed civil war likely?
The end of the Second Sino-Japanese War and the post-war balance, including the Soviet invasion of Manchuria, the race for territory, the Chongqing negotiations, and the Marshall Mission
A focused answer on the Japanese surrender (August-September 1945), the Soviet invasion of Manchuria, the race for Japanese-held territory between KMT and CCP, the Chongqing Negotiations (October 1945), and the Marshall Mission (December 1945 to January 1947). Covers Yalta, the Sino-Soviet Treaty (August 1945), and the historiography of Westad and Pepper.

What this dot point is asking
NESA expects you to explain the situation at the Japanese surrender, the race for Japanese-held territory between the KMT and CCP, and the failure of negotiation under the Chongqing talks and the Marshall Mission to prevent renewed civil war. Strong answers integrate the Soviet invasion, the Yalta-Sino-Soviet Treaty, the US airlift, and the underlying structural incompatibility.
The answer
Japan's collapse
The Japanese Empire entered 1945 in industrial collapse. The B-29 firebombing of Tokyo (9-10 March 1945) killed around 100,000. By June, Japan had lost the Philippines, Iwo Jima, and Okinawa. The Potsdam Declaration (26 July 1945) demanded unconditional surrender.
The atomic bombings (Hiroshima 6 August, Nagasaki 9 August) and Soviet entry into the war (8 August) broke the Cabinet's resistance. Emperor Hirohito recorded the surrender broadcast on 14 August; it was broadcast on 15 August 1945 (V-J Day). The formal surrender was signed aboard USS Missouri in Tokyo Bay on 2 September 1945.
The Soviet invasion of Manchuria
Stalin had promised at Yalta (4-11 February 1945) to enter the Pacific war within three months of Germany's surrender. Operation August Storm launched on 9 August 1945 with around 1.5 million Soviet troops under Marshal Aleksandr Vasilevsky. The Kwantung Army (around 700,000 troops, equipped at 1941 levels) collapsed within two weeks. Soviet forces overran Manchuria, north Korea, and Karafuto. Around 600,000 Japanese prisoners were taken to Soviet camps.
Soviet policy toward Yan'an
Stalin's formal policy was pro-KMT. The Sino-Soviet Treaty of Friendship and Alliance (14 August 1945) recognised the KMT government, accepted KMT sovereignty over Xinjiang and Manchuria, and in return reasserted Soviet naval and railway rights in Manchuria (Port Arthur, Dairen, joint railway operation), as Yalta had promised.
In practice the Red Army in Manchuria handed huge quantities of Japanese arms to Lin Biao's CCP forces. The 700,000 rifles, 14,000 light and heavy machine guns, around 4,000 artillery pieces, and 700 tanks of the Kwantung Army's arsenal that ended up in CCP hands transformed Lin Biao's force from a guerrilla army into a conventional one. Stalin's double game reflected both Yalta obligations and his desire to keep Chiang weak.
The race for territory
Japanese forces in China proper numbered around 1.05 million, plus 900,000 collaborationist troops; with Manchurian Kwantung Army, the total was around 2.6 million surrendering Japanese. The question was who took the surrender.
US policy was clear: General Order Number 1 (15 August 1945) instructed Japanese forces in China (excluding Manchuria) to surrender to the KMT. The US Air Transport Command airlifted around 500,000 KMT troops to north China cities (Beijing, Tianjin, Shanghai, Nanjing) over the next three months. US Marines temporarily garrisoned Tianjin, Beijing, and other northern cities.
CCP forces under Zhu De ordered Japanese garrisons to surrender to them; most refused and waited for the KMT. But in the countryside between the cities, CCP forces moved in, accepted local Japanese and collaborationist surrenders, and acquired weapons. The CCP took control of perhaps 250,000 square kilometres in Manchuria, north China, and central China by late 1945.
The Chongqing Negotiations
Mao flew to Chongqing on 28 August 1945 under US escort (General Patrick Hurley personally accompanied him). The visit, his first to Chongqing, was a political risk balanced by enormous publicity value. Talks ran from 28 August to 10 October 1945.
The Double Tenth Agreement (10 October 1945) committed both sides to:
- A "free and democratic" China.
- A Political Consultative Conference to plan the post-war state.
- Recognition of "the equal and legal status of all political parties."
- Demobilisation and integration of armed forces.
- Local elections.
The terms were not enforceable. Fighting in Shanxi between Yan Xishan's forces (KMT-aligned) and CCP units broke out as Mao flew home. The agreement died on paper.
The Marshall Mission
President Truman dispatched General George C. Marshall as Special Envoy on 27 November 1945. Marshall's mandate was to broker a coalition government and avert civil war.
Marshall's first cease-fire (10 January 1946) was substantially honoured for several months. The Political Consultative Conference (10-31 January 1946) agreed on principles for a coalition. The PCCRC plan (February 1946) called for integrating CCP and KMT forces in a 10:50 ratio over eighteen months.
Both sides reneged. KMT hardliners (the CC clique, the Whampoa clique) saw the plan as surrendering KMT advantages. CCP hardliners saw it as surrendering political autonomy. Fighting in Manchuria (Siping, April-May 1946) became major war. By June 1946 Marshall conceded failure. He returned to Washington in January 1947, having identified KMT corruption and CCP intransigence in roughly equal measure.
Conditions for war
By summer 1946:
- The KMT had around 4.3 million troops, the modern German and US-trained core, US Lend-Lease equipment, and nominal control of all major cities and railways.
- The CCP had around 1.2 million regulars, 2.6 million militia, base areas covering around 100 million people, and the Japanese arsenal acquired in Manchuria.
- The US had given up on a negotiated settlement; Soviet aid to the CCP was active but covert.
Renewed full-scale civil war was a matter of weeks.

How to read a source on this topic
Sources include the Yalta protocols, the Sino-Soviet Treaty, the Double Tenth Agreement, Marshall's reports, contemporary US press coverage (Henry Luce's Time was pro-KMT, the New York Times more balanced), and CCP press from Yan'an. Three reading habits.
First, separate Soviet rhetoric from Soviet action. Stalin signed a treaty with the KMT and supplied the CCP. The double game served Moscow's interest in keeping China weak and divided.
Second, treat the Marshall Mission as the moment of US policy choice. Marshall's failure foreclosed any coalition solution; his report shaped the Truman administration's reluctance to invest further in Chiang.
Third, follow the Manchurian weapons. The numerical fall of the KMT in 1948 is unintelligible without the Japanese arms transferred to Lin Biao in late 1945.
Examples in context
Example 1. The Soviet invasion of Manchuria (9 August 1945). Operation August Storm deployed 1.5 million Soviet troops and destroyed the Kwantung Army within ten days. The Soviets transferred captured Japanese weapons (around 740 aircraft, 600 tanks, and rifles for 300,000 troops) to the CCP forces under Lin Biao. Steven I. Levine (Anvil of Victory, 1987) treats the Soviet contribution as decisive in Manchuria. Hans van de Ven (China at War, 2017) emphasises the conditional and time-limited nature of Soviet help.
Example 2. The Marshall Mission (December 1945 to January 1947). George C. Marshall mediated KMT-CCP negotiations under the Chongqing Double Tenth Agreement (10 October 1945). His failed mission report (January 1947) blamed both sides. Daniel Kurtz-Phelan (The China Mission, 2018) draws on Marshall's papers to argue the mission failed because neither side believed war could be avoided. The Chinese Civil War resumed in earnest from mid-1946.

Practice (NESA)10 marksWhy did civil war between the Nationalists and Communists resume after 1945?Show worked answer →
A 10-mark "why" answer needs developed causes and a named historian.
- Thesis
- Civil war resumed because the Japanese surrender created a power vacuum that both sides intended to fill on their own terms; the Chongqing Negotiations and Marshall Mission failed to overcome the basic incompatibility between KMT centralisation and CCP base-area autonomy backed by 1.2 million troops.
- The Japanese surrender
- Japan surrendered 15 August 1945 (formally 2 September) after the atomic bombings and Soviet invasion of Manchuria. Three million Japanese troops in China and Manchuria laid down arms.
- Race for territory
- US airlift moved 500,000 KMT troops to north China cities; Soviet forces in Manchuria allowed CCP units to occupy the countryside and seize around 700,000 Japanese rifles, plus tanks and artillery.
- Sino-Soviet Treaty (14 August 1945)
- Stalin recognised KMT sovereignty in Manchuria and Xinjiang in return for Soviet rights to Port Arthur, Dairen, and the Manchurian railways.
- Chongqing Negotiations
- Mao flew to Chongqing 28 August. The Double Tenth Agreement (10 October 1945) was unenforceable.
- Marshall Mission (Dec 1945-Jan 1947)
- Marshall brokered a January 1946 cease-fire; both broke down by mid-1946. Manchuria fighting (April-June 1946), then full civil war.
- Underlying causes
- Incompatible projects: centralised one-party state versus a peasant-revolutionary federation backed by 1.2 million CCP troops.
- Historiography
- Westad (2003), Pepper (1978), Levine (1987). Markers reward the territory race, the Marshall Mission, and the underlying incompatibility.
Practice (NESA)5 marksExplain the significance of the Soviet invasion of Manchuria in August 1945.Show worked answer →
A 5-mark "explain" answer needs three points.
- Military
- Stalin honoured the Yalta agreement by declaring war on Japan on 8 August 1945 and launching Operation August Storm on 9 August. Around 1.5 million Soviet troops under Marshal Vasilevsky overran the Kwantung Army (around 700,000) in two weeks. Japanese surrenders in Manchuria were taken by the Soviets, not the KMT.
- Strategic effect for the CCP
- Soviet forces deliberately allowed CCP units, especially Lin Biao's Northeast Democratic United Army (renamed Fourth Field Army in 1948), to move into Manchuria and acquire Japanese arms. Around 700,000 captured Japanese rifles, plus heavier weapons, transformed CCP firepower.
- Manchuria as the decisive theatre
- Manchuria's industry (heavy industry built up under Manchukuo), railways, and proximity to Soviet supply made it the ideal CCP base. The decisive Liaoshen Campaign of 1948 won the civil war in the north-east before the south fell.
Markers reward 9 August, the Kwantung Army figures, and the Japanese arms transfer.

Original practice questions graded from foundation to exam level, each with a full worked solution. Try them before revealing the solution.
foundation3 marksOutline the situation in China at the Japanese surrender in August 1945.Show worked solution →
A 3-mark "outline" wants three distinct, dated features.
- The surrender
- Japan announced its surrender on 15 August 1945 (formally 2 September), leaving around 2.6 million Japanese and collaborationist troops in China and Manchuria to lay down arms.
- The Soviet factor
- Operation August Storm (9 August 1945) had overrun Manchuria; Soviet forces held the north-east and the Japanese arms there.
- The race for territory
- Both the KMT and CCP rushed to take the Japanese surrender and seize the weapons, cities, and territory the Japanese vacated.
- Marking criteria
- 1 mark each for three distinct, correctly dated features; do not narrate the later civil war.
foundation4 marksExplain how the Soviet invasion of Manchuria affected the post-war balance between the KMT and CCP.Show worked solution →
A 4-mark "explain" needs a cause-and-effect chain with specific detail.
- The invasion
- Operation August Storm (9 August 1945) deployed around 1.5 million Soviet troops and destroyed the 700,000-strong Kwantung Army within about two weeks, so the Soviets, not the KMT, took the Japanese surrender in Manchuria.
- The arms transfer
- Stalin's forces let Lin Biao's CCP units move into Manchuria and acquire around 700,000 captured Japanese rifles, plus around 4,000 artillery pieces and around 700 tanks.
- The effect
- This transformed the CCP in the north-east from a guerrilla force into a conventional army with an industrial base, while diplomatically the Sino-Soviet Treaty (14 August 1945) still recognised the KMT - Stalin's double game.
- Marking criteria
- 1 mark for the invasion/Kwantung Army; 1 mark for the arms transfer; 1 mark for the conventional transformation; 1 mark for linking to the wider balance (or the double game).
foundation4 marksWhy did the Chongqing Negotiations and the Double Tenth Agreement fail to secure peace?Show worked solution →
A 4-mark "why" needs developed reasons, not narration.
- A risk balanced by publicity
- Mao flew to Chongqing on 28 August 1945 under US escort; the talks (28 August to 10 October) produced the Double Tenth Agreement promising a "free and democratic" China and army integration.
- Unenforceable terms
- Nothing in the agreement bound either side: there was no mechanism to demobilise armies or compel elections, and fighting in Shanxi between Yan Xishan's KMT-aligned forces and CCP units broke out even as Mao flew home.
- Incompatible projects
- The KMT wanted a centralised one-party state; the CCP would not surrender its base-area autonomy or its 1.2 million troops.
- Marking criteria
- 1 mark for dating Chongqing; 1 mark for the unenforceable terms; 1 mark for the Shanxi fighting; 1 mark for the underlying incompatibility.
core5 marksSource A (paraphrased, owned): A historian of the Manchurian theatre argues that the Soviet occupation of Manchuria in late 1945 was the single most important external factor in the Communist victory, because the Red Army's transfer of the Kwantung Army's arsenal converted Lin Biao's forces from scattered guerrillas into an army capable of conventional campaigns.
Using Source A and your own knowledge, explain the significance of the Soviet role in Manchuria in 1945. [5 marks]
Show worked solution →
A 5-mark "explain ... using the source" wants the source decoded, then linked to own knowledge.
- Decode the source
- Source A reflects the position of Steven Levine (Anvil of Victory, 1987): it foregrounds the Soviet weapons transfer as the decisive external factor and frames Manchuria as the place the CCP was rebuilt into a conventional force.
- Corroborate with own knowledge
- Operation August Storm (9 August 1945) destroyed the Kwantung Army; the Red Army then let Lin Biao's units acquire around 700,000 rifles, around 4,000 artillery pieces, and around 700 tanks. Manchuria's heavy industry and railways gave the CCP a logistical base, and the decisive Liaoshen Campaign of 1948 was won there first.
- Add a limitation
- The Soviet role was double-edged: diplomatically Stalin signed the Sino-Soviet Treaty recognising the KMT, and Hans van de Ven stresses that Soviet help was conditional and time-limited rather than open-ended.
- Marking criteria
- 1 mark for placing the source's interpretation; 1-2 marks for own knowledge on the arms transfer and Manchurian base; 1 mark for the diplomatic double game; 1 mark for a balanced judgement on significance.
core5 marksSource B (paraphrased, owned): In his final report on leaving China, General Marshall blamed the failure of mediation on irreconcilable groups on both sides - a dominant reactionary clique within the KMT and hardline elements within the CCP - who placed their own positions above any genuine coalition.
Using Source B and your own knowledge, assess the usefulness of this source for understanding why the Marshall Mission failed. [5 marks]
Show worked solution →
A 5-mark "assess the usefulness" rewards origin/perspective plus own knowledge, ending in a judgement.
- Origin and perspective
- Source B is George C. Marshall's own farewell statement (January 1947), so it carries the authority of the chief mediator but also a participant's interest in spreading the blame evenly rather than admitting US limits.
- Corroboration from own knowledge
- It fits the record: the January 1946 cease-fire and the PCC framework (1:5 army-integration ratio) collapsed because KMT hardliners (the CC and Whampoa cliques) saw the plan as surrendering their advantages, while CCP hardliners would not surrender base-area autonomy. Fighting at Siping (April-May 1946) reopened the war.
- Limitation
- As a participant Marshall understates the structural drivers - the territory race already underway and Soviet arms in Manchuria - which Westad treats as more decisive than personalities.
- Judgement
- Highly useful as direct testimony to the "both sides chose to fight" thesis, but it must be read alongside the structural account, since Marshall has reason to frame the failure as Chinese intransigence rather than an unwinnable situation.
- Marking criteria
- 1 mark for origin/perspective (Marshall's own report); 1-2 marks for own knowledge corroborating the breakdown; 1 mark for a limitation; 1 mark for a judgement on usefulness.
exam25 marksEvaluate the extent to which the post-war balance of 1945 to 1946 made renewed civil war in China inevitable.Show worked solution →
This is an extended-response/essay. Markers reward a sustained, evidence-based argument that addresses "to what extent" and weaves in historiography - not a narrative.
Band-6 PLAN
- Thesis. The post-war balance made civil war highly likely but not strictly inevitable: the Japanese surrender, the Soviet occupation of Manchuria, and the race for territory built two armed states inside one country, while the Chongqing and Marshall negotiations failed because neither side's project could be reconciled. Structure pushed hard towards war, but the choice to fight was still made by leaders who rejected coalition.
- Argument 1 - The power vacuum and the territory race (structure pushing to war). Japan's collapse (15 August 1945) left around 2.6 million troops to disarm and a vacuum both sides meant to fill. The US airlifted around 500,000 KMT troops to the cities under General Order Number 1, while the CCP took the countryside - two interlocking occupations primed for collision.
- Argument 2 - Manchuria and the Soviet double game. Operation August Storm (9 August) handed the CCP the Kwantung Army's arsenal (around 700,000 rifles, 700 tanks), converting Lin Biao's force into a conventional army, even as the Sino-Soviet Treaty (14 August) recognised the KMT. The external balance armed the very confrontation diplomacy claimed to prevent.
- Argument 3 - Why negotiation could not hold (the element of choice). The Double Tenth Agreement (October 1945) and the Marshall cease-fire (January 1946) were unenforceable because the parties' projects were incompatible: a centralised one-party KMT state versus a peasant-revolutionary federation with 1.2 million troops. Siping (April-May 1946) showed both sides would fight rather than integrate armies.
- Historiography. Odd Arne Westad (Decisive Encounters, 2003) reads the outcome as decided by structural and strategic factors rather than personalities; Suzanne Pepper (Civil War in China, 1978) stresses the political failure to build a viable coalition; Daniel Kurtz-Phelan (The China Mission, 2018) argues from Marshall's papers that mediation failed because neither side believed war could be avoided - restoring an element of choice.
- Judgement. Weigh structural drivers (Westad - vacuum, territory, Manchurian arms) against contingency (Kurtz-Phelan - the parties chose war). The balance made war the overwhelmingly probable outcome, but it became certain only when the leaders rejected the coalition Marshall offered. Highly likely, not mechanically inevitable.
MODEL PARAGRAPH (Argument 3)
The strongest case that civil war was not quite inevitable lies in the negotiations that almost held. The Double Tenth Agreement of 10 October 1945 committed both sides to a "free and democratic" China and to integrating their armies, and Marshall's cease-fire of 10 January 1946 was substantially honoured for several months while the Political Consultative Conference drew up a coalition framework, including a plan to merge CCP and KMT forces in a 1:5 ratio. That such accords were reached at all shows the outcome was contested rather than predetermined. Yet they were unenforceable: there was no mechanism to compel demobilisation, and the projects behind the two armies could not be reconciled - the KMT demanded a centralised one-party state while the CCP would not surrender the base-area autonomy that 1.2 million troops protected. When major fighting reopened at Siping in April 1946, it confirmed that both sides preferred war to integration. As Daniel Kurtz-Phelan argues from Marshall's papers, the mission failed less because mediation was clumsy than because neither side believed war could be avoided - a judgement that keeps the element of choice in view without denying the structural pressures driving it.
Marker's note. A band-6 response keeps "to what extent ... inevitable" in view throughout - weighing structural drivers against contingency rather than narrating events - anchors every claim in dated evidence, sets at least two historians in genuine tension (structure vs choice), and reaches a graded judgement. Narrating 1945-1946 without arguing the inevitability question caps the response in the middle bands.
exam25 marksAssess the view that the Soviet Union, rather than the United States, was the more decisive external power in shaping post-war China by 1946.Show worked solution →
This is an extended-response/essay. Markers reward a sustained, comparative argument with historiography - not a narrative of both powers.
Band-6 PLAN
- Thesis. The Soviet Union was the more decisive external power because its occupation of Manchuria rearmed the CCP into a conventional force and handed it the decisive theatre, whereas US intervention (the airlift, the Marshall Mission) shored up the KMT's positions but could neither win the territory race outright nor impose a settlement. Both mattered; the Soviet contribution was the more lasting.
- Argument 1 - The Soviet contribution (the decisive factor). Operation August Storm destroyed the Kwantung Army and transferred its arsenal (around 700,000 rifles, around 700 tanks, around 4,000 artillery pieces) to Lin Biao; Manchuria's industry and railways became the CCP base from which the 1948 Liaoshen Campaign was won. Stalin's diplomatic cover (the Sino-Soviet Treaty) cost the CCP nothing on the ground.
- Argument 2 - The US contribution (real but limited). The US airlifted around 500,000 KMT troops to north China and garrisoned cities with Marines under General Order Number 1, securing the urban surrender. But the Marshall Mission could not impose a coalition, and US aid declined as Marshall left in January 1947 having blamed both sides.
- Argument 3 - Weighing the two. US help secured cities the KMT then could not hold; Soviet help built the field army that destroyed the KMT's modern divisions. The decisive theatre (Manchuria) and the decisive arms came from the Soviet side; the US effort propped up a structure that was already failing.
- Historiography. Steven Levine (Anvil of Victory, 1987) treats the Soviet-enabled Manchurian base as decisive; Hans van de Ven (China at War, 2018) cautions that Soviet help was conditional and time-limited; Daniel Kurtz-Phelan (The China Mission, 2018) shows the limits of US leverage through Marshall's failure.
- Judgement. Levine's emphasis carries more weight than the US-centred reading: the Soviet arms and the Manchurian base shaped the military outcome, while US intervention delayed rather than reversed the KMT's decline. Soviet, not US, power was the more decisive - though van de Ven's caution against overstating Soviet generosity should be acknowledged.
MODEL PARAGRAPH (Argument 1)
The Soviet occupation of Manchuria did more to shape post-war China than any US action, because it rebuilt the Communist army into a force that could fight conventional campaigns. When Operation August Storm overran the Kwantung Army in August 1945, the Red Army took the Japanese surrender across the north-east and then allowed Lin Biao's units to move in and acquire the captured arsenal - around 700,000 rifles, some 4,000 artillery pieces, and around 700 tanks - alongside the heavy industry and railways the Japanese had built under Manchukuo. As Steven Levine argues in Anvil of Victory (1987), this transfer converted a guerrilla force into a conventional army with an industrial base, and it was in Manchuria that the decisive Liaoshen Campaign of 1948 was won before the south fell. Crucially, Stalin paid no diplomatic price for this: the Sino-Soviet Treaty of 14 August 1945 publicly recognised the KMT, so the double game armed the CCP while costing Moscow nothing. US intervention, by contrast, could airlift KMT troops into cities but could not give them an army able to hold the field.
Marker's note. A band-6 response sustains the comparison throughout (always weighing Soviet against US influence rather than describing each), anchors claims in dated evidence, deploys at least two historians in genuine tension (Levine's "Soviet decisive" against van de Ven's caution), and reaches a graded judgement. Describing both powers without ranking them caps the response in the middle bands.
