Why did China and the Soviet Union split?

The dispute was framed as peaceful coexistence versus revolutionary struggle, but it was really about leadership of the socialist camp, borders and nuclear aid.

Why does Bandung matter?

It let newly independent Asian and African states appear as a third force and became the base of the later non-aligned movement.

03　Answers and one-line notes

#	Answer	One-line note
1	The People’s Republic of China was founded while the United States backed the Nationalists on Taiwan, leaving two camps facing each other	The change of government on the mainland stretched the American containment line from Europe to the western Pacific, with Taiwan as the front.
2	The Sino-Soviet Treaty of Friendship, Alliance and Mutual Assistance, with loans, technology, advisers and military aid	The treaty made Washington treat Beijing and Moscow as one bloc and became the sharpest point of contrast once they split.
3	To contain communist expansion in Southeast Asia, with the United States, Britain, France, Australia, New Zealand, the Philippines, Thailand and Pakistan as members	SEATO rested on the Manila Pact but had no standing force, so its real deterrent value was limited.
4	It was the first large meeting of twenty-nine Asian and African states, setting out the Five Principles of Peaceful Coexistence and a non-aligned stance	The conference let newly independent states claim a third position outside both NATO and the Warsaw Pact.
5	1 year	1950 minus 1949 is one year, so Beijing aligned with Moscow within a year of founding the state.
6	19 years	1969 minus 1950 is nineteen years, in which allies turned into border combatants and the split was complete.
7	23 years	1977 minus 1954 is 23 years, and after the Vietnam War the regional setting changed and the alliance lapsed.
8	That the unity was declaratory, since border, territorial and ideological disputes persisted and India and China quickly became rivals	1962 minus 1955 is seven years, and non-alignment could not restrain bilateral disputes because national interest outran the slogan of solidarity.
9	Sporting contact broke a freeze of over twenty years, and the United States used the Sino-Soviet split to court China, creating a triangular balance	Washington gained leverage to exit Vietnam and balance Moscow, while Beijing escaped encirclement by both powers.
10	Close in the 1950s, openly divided over ideology in the 1960s, and in armed clash at Zhenbao Island in 1969, so the alliance was hollow	The split grew from disputes over ideology and leadership of the socialist camp, not from a single border incident.
