After 1945, the Cold War did not stay in Europe. In Asia it turned into real shooting wars, fought over which side newly independent or colonised peoples would join: the communist bloc or the western one. The first of these was in Malaya, a British colony rich in rubber and tin.
Why Malaya mattered: Malaya supplied Britain with huge dollar earnings from rubber and tin exports. Losing it to communism would have been a strategic and economic disaster for a Britain still rebuilding after the Second World War.
The Malayan Communist Party (MCP), led by Chin Peng, had fought the Japanese occupation during the war and expected political reward afterwards. When the British instead moved slowly toward self-government under continued colonial control, the MCP turned to armed struggle in 1948, forming the Malayan Races' Liberation Army. Britain declared a state of emergency that would last twelve years.
- MCP support base — mostly ethnic Chinese squatters on the jungle fringe, who felt excluded from Malay-dominated politics and land rights
- Guerrilla tactics — ambushes on rubber plantations and tin mines, sabotage, assassination of colonial officials and Malay leaders
- Aim — force the British out and establish a communist Malayan republic
The British/Commonwealth response
Britain treated Malaya as a police and political problem, not just a military one. General Templer, appointed in 1952, combined tough security measures with reforms designed to win over the population — a strategy later called hearts and minds.
The Briggs Plan (1950)
Resettled around 500,000 rural Chinese squatters into fortified "New Villages" with land, schools and clinics — cutting the MCP off from its food and recruit supply.
Military pressure
Commonwealth troops (British, Gurkha, Australian, New Zealand, Fijian) hunted MCP units in the jungle; food controls starved out remaining fighters.
Political reform
Elections were promised and citizenship was widened, so Malayans had a peaceful path to change rather than only the MCP's path.
Independence (1957)
Malaya became independent under Tunku Abdul Rahman, a non-communist, pro-western leader — removing the MCP's central demand.
Cut the supply, promise the vote, and the rebellion starves.
Resolution and legacy: The Emergency officially ended in 1960 with the MCP defeated militarily and politically outmanoeuvred. It became the model "hearts and minds" counter-insurgency — reforms alongside force — that other western powers (not always successfully) tried to copy in Vietnam.

Korea had been split at the 38th parallel in 1945 when Japan surrendered — Soviet troops occupied the north, American troops the south. By 1948 this had hardened into two rival states: communist North Korea under Kim Il-sung, and anti-communist South Korea under Syngman Rhee. Both leaders wanted to reunify the peninsula under their own rule.
- Kim Il-sung's confidence — persuaded Stalin and Mao that a quick invasion could reunify Korea before the US intervened
- US withdrawal signals — Secretary of State Dean Acheson's 1950 speech seemed to place Korea outside America's defensive perimeter
- Cold War context — Mao's victory in China (1949) and the Soviet atomic bomb (1949) made the communist bloc feel emboldened
On 25 June 1950, North Korean forces invaded the south, quickly overrunning most of the peninsula. The United Nations Security Council — with the Soviet Union boycotting the Council and unable to veto — approved a US-led multinational force to defend South Korea under General Douglas MacArthur.
North Korean invasion
June 1950: North Korean troops push south, capturing Seoul within days and trapping UN/South Korean forces in the Pusan perimeter.
Inchon landing
September 1950: MacArthur's daring amphibious landing at Inchon cuts off North Korean supply lines and reverses the war almost overnight.
Push to the Yalu
UN forces cross the 38th parallel and advance toward the Chinese border, alarming Beijing about a hostile power on its doorstep.
Chinese intervention
October 1950: hundreds of thousands of Chinese "People's Volunteers" cross the Yalu River, driving UN forces back and retaking Seoul.
Stalemate
By mid-1951 the front line settles near the 38th parallel; two more years of fighting change little on the map.
Invade, land, push, counter-punch, stalemate.
International responses: Korea became the clearest example of proxy war: the USA and 20 other UN member states backed the South, while China supplied troops and the USSR supplied weapons, aircraft and pilots to the North — all without the superpowers fighting each other directly.

The Korean War ended not with a peace treaty but with the Armistice Agreement (27 July 1953), signed at Panmunjom. It created a new demilitarised zone (DMZ) close to the original 38th parallel border — meaning three years of war had changed almost nothing on the map, at a huge human cost.
| Impact | Details |
|---|---|
| Human cost | Around 3 million Korean deaths (civilian and military); tens of thousands of US and Chinese losses |
| Political impact | Korea remained divided at almost the same line as before the war — division became permanent |
| Economic impact | Both North and South devastated; South Korea took decades to rebuild, later becoming a major economy |
| Cold War impact | Confirmed containment as US policy; increased US defence spending and military presence in Asia |
No formal peace treaty: Technically North and South Korea are still at war — the 1953 agreement was only an armistice (ceasefire), never a full peace treaty.
While Korea was dividing along a Cold War line drawn by outside powers, a separate but related struggle was building in French Indo-China (Vietnam, Laos and Cambodia). Vietnamese nationalism had been growing since the 1930s, but the Second World War gave it its decisive leader and organisation.
- Ho Chi Minh — Vietnamese communist and nationalist leader, founder of the Indochinese Communist Party, who spent decades abroad before returning to lead the independence movement
- Viet Minh — short name for the League for the Independence of Vietnam, founded by Ho Chi Minh in 1941 to fight both Japanese occupation and French colonial rule
- September 1945 — Ho Chi Minh declares Vietnamese independence in Hanoi, deliberately echoing the American Declaration of Independence to appeal to US support
France, however, was determined to restore its colonial empire after the humiliation of defeat in 1940. Negotiations between the Viet Minh and France collapsed, and fighting broke out in late 1946 — the start of the French Indo-China War (1946-1954).
French strategy
France relied on conventional firepower and fortified bases, expecting to crush what it saw as a small colonial rebellion rather than a mass national movement.
Viet Minh strategy
Ho Chi Minh's general, Vo Nguyen Giap, built a guerrilla army that avoided open battle early on, winning peasant support through land reform promises and patient, protracted warfare.
Cold War overlay
After 1949-1950, China and the USSR armed the Viet Minh, while the USA funded up to 80% of France's war costs — turning a colonial war into another Cold War front.
Why this matters for Part 2: The French Indo-China War ended in 1954 with French defeat at Dien Bien Phu and the Geneva Accords, which temporarily divided Vietnam at the 17th parallel. That division — and the unfinished promise of unification elections — is exactly what ignites the Vietnam War (1956-1975), covered in the next micro.
