Why did the UN front the Korean War?

The Security Council authorised members to help South Korea while the Soviet Union was absent and could not veto, so the United States led a UN command.

How did the embargo force Hong Kong to change?

Re-exports to the mainland stopped, so the colony had to make and sell its own goods, which started industrial growth.

03　Answers and one-line notes

#	Answer	One-line note
1	It began in 1950 and an armistice was signed in 1953	The war lasted three years and ended with the armistice at Panmunjom, leaving the peninsula divided near the 38th parallel.
2	The United States	The Security Council authorised force, but the fighting and command were overwhelmingly American with smaller allied contingents.
3	21 years	1975 minus 1954 is 21 years, ending with the fall of Saigon and the reunification of Vietnam.
4	It divided the country at the 17th parallel pending nationwide elections that were never held	The conference ended French fighting in Indochina, but the promised elections never took place and the partition bred a long conflict.
5	Entrepot trade collapsed and Hong Kong was forced into manufacturing its own exports	Hong Kong lived on re-exports, so the embargo killed that trade and pushed the colony into light manufacturing for export.
6	1971	A 1971 General Assembly resolution gave the China seat to Beijing and removed the Taipei representatives.
7	A visit in 1972 and formal ties in 1979, seven years apart	1979 minus 1972 is 7 years, and normalisation reshaped the Cold War balance in Asia.
8	The two blocs backed South and North Vietnam respectively while avoiding direct all-out war with each other	Both sides supplied money, weapons and advisers, so the ideological struggle was fought on a third country’s soil.
9	Ground troops poured in, the anti-war movement grew, and US forces withdrew after the 1973 Paris agreement	Escalation divided American society, and after the 1973 Paris agreement the troops left and the South fell in 1975.
10	North Korea attacked, the Soviet Union supplied arms and advisers without sending combat troops, and China later sent volunteers	Each played a different part: North Korea attacked, the Soviet Union armed and advised, and Chinese volunteers pushed the line back to the 38th parallel.
